Abstract: Polymeric articles containing at least one polymeric material and a sufficient amount of at least one novel hindered amine light stabilizers to inhibit at least one of photo- or thermal degradation. The hindered amine light stabilizer may be a monomeric or an oligomeric hindered amine light stabilizer.

Description: POLYMERIC ARTICLES CONTAINING HINDERED AMINE LIGHT STABILIZERS BASED ON MULTI-FUNCTIONAL CARBONYL COMPOUNDS FIELD OF THE INVENTION This invention relates generally to novel hindered amine light stabilizers (HALS) and their use as a protectant against ultraviolet radiation or light ("UV light"). Also included are concentrates and articles including such stabilizers, and methods of making all of the above. BACKGROUND It is well known that ultraviolet ("UV") light or radiation, especially sunlight, can cause degradation of a variety of materials, especially polymeric materials. Often this results in embrittlement or yellowing of the materials, which may be in the form of molded articles, extruded articles, films, tapes, coatings, or the like. However, this degradation can be inhibited by the incorporation of light stabilizers in, or on, the polymeric articles. The most commonly used stabilizers are UV-absorbers, hindered amine light stabilizers ("HALS"), and phenolic and non-phenolic antioxidants. HALS scavenge free radicals formed in polymeric material when the material is exposed to UV light. The functional component of the HALS molecule is typically the 2,2,6,6-tetraalkylpiperidine moiety. Typically, the 2,2,6,6- tetraalkylpiperidine moiety is anchored to a carbonyl or melamine functional group (See, e.g. , U.S. Patent Nos. 4,331,586; 3,840,494; Re. 31,342; Re. 30,385; 3,640,928; 4,086,204; 4,265,805). Anchoring the 2,2,6,6-tetraalkylpiperidine moiety to a carbonyl or melamine functional group typically lowers the volatility and extractability of a stabilizer. Low volatility is an important characteristic of light stabilizers in applications where high temperatures are encountered, which occurs frequently in the processing of thermoplastics and in the curing of thermoset resins and coatings. Often, high temperatures are also present in the end-use applications for the stabilized material. Low volatility helps prevent loss of the stabilizer during processing, curing, and high temperature end uses. Typically, HALS molecules containing the 2,2,6,6- tetraalkylpiperidine group anchored to a carbonyl group are made by reacting a 2,2,6,6- tetraalkylpiperidin-4-ol or 4-amino-2,2,6,6-tetramethylpiperidine with a carboxylic acid chloride or ester. U.S. Patent Nos. Re. 31,342, 4,021,432 and 4,049,647 disclose a class of 1- and 4- substituted piperidines that are stabilizers for organic materials. The stabilizers are produced by reacting the corresponding 1 -substituted piperidinols with acid chlorides, or the corresponding 4-substituted piperidines, with a compound introducing a residue into the 1 -position of the piper idine moiety. U.S. Patent No. 3,840,494 discloses a polymer composition stabilized against photo- and thermal deterioration by incorporating therein acid esters of 4- piperidinol derivatives in an amount sufficient to prevent such deterioration. The acid esters of the 4-piperidinol derivatives are prepared by reacting the 4-piperidinol derivative with a carboxy late ester in xylene with sodium hydroxide. For example, the reaction of 4-hydroxy-2,2,6,6-tetramethylpiperidine with ethyl benzoate produces 4- benzoy loxy-2 ,2,6, 6-tetramethy lpiperidine . Similarly, the 2,2,6,6-tetramethylpiperidin-4-ol can be reacted with diesters or diacid chlorides to produce diester-HALS. Also, the 2,2,6,6- tetramethylpiperidin-4-ol can be reacted with a diisocyanate to produce a diurethane- HALS. However, the relatively high cost of dusocyanates makes them less practical than diesters when preparing HALS. Compounds which have an ester functionality at one terminus of a hydrocarbon chain and a urethane functionality at the other terminus of the hydrocarbon chain (alkoxycarbonylamino alkanoates) are known for various other uses other than light stabilization and can be prepared by a variety of synthetic schemes (See, e.g., Effenberger, F.; Drauz, K.; Foerster, S.; Mueller, W., Chem. Ber., 114(1), 173-89; Dixit, A.; Tandel, S.; Rajappa, S.; Tett. Lett.; 35(33), 6133-4, Duong, et al., Aust. J. Chem., 29, 2651-61, 1976; Iwaka et al., J. Org. Chem., 31, 142-46, 1966; Taub; Hino; J. Chem. Eng. Data, 9, 106, 1964; U.S. Patent No. 5,300,678 to Merger et al.). U.S. Patent No. 5,574,162 discloses 1-hydrocarbyloxy substimted HALS, which also contain reactive functional groups that chemically attach to selected polymer substrates by condensation reactions. Oligomeric HALS are also known. For example, TINUVIN 622 is a commercially available oligomeric HALS produced by Ciba Specialty Chemicals Inc. of Hawthorne, NY. TINUVIN 622 can be produced by the reaction of dimethyl succinate with N-(2-hydroxyethyl)-2,2,6,6-tetramethyl-4-piperidinol. U.S. Patent No. 4,223,412 discloses condensation and addition polymers wherein the recurrent molecular unit contains a polyalkylpiperidine radical that are useful as light stabilizers for plastics. In one embodiment the copolymer is formed by copolymerization or copolycondensation of polyalkylpiperidine containing monomers with polyalkylpiperidine free monomers such as caprolactam. U.S. Patent No. 6,271,377 discloses HALS which are substituted on the N-atom by N-alkyloxy moieties containing one to three hydroxyl groups. U.S. Patent No. 4,331,586 to Hardy discloses oligomers that contain at least one piperidyl moiety in the repeating unit for use as light stabilizers. While providing protection for polymeric materials, such as polypropylene, polymeric films containing the disclosed oligomeric HALS became brittle after exposure to UV light for about 1,700 hours. HALS compounds may be used individually or in combination with other light stabilizers to inhibit photodegradation of polymers. For example, UV light absorbers, such as benzotriazoles and benzophenones, were initially used to stabilize polymeric materials and to prevent degradation of such materials from exposure to UV light. Later, it was discovered that HALS compounds were more effective than UV light absorbers alone, and thus, UV light absorbers are presently used in combination with at least one HALS compound in most conventional applications (See, e.g. , United States Patent Nos. 4,740,542; 4,619,956; 5,461,151; 5,721,298). Similarly, HALS compounds are often employed in combination with other stabilizers, such as antioxidants (See, e.g. , United States Patent No. 4,722,806). Combining the HALS with another stabilizer may provide a polymeric material with better resistance to weathering. U.S. Patent No. 4,619,956 discloses a method of stabilizing a polymer film, coating, or molded article against the action of light, moisture and oxygen by incorporating a HALS compound and a tris-aryl-s-triazine UV light absorber into a polymer. Preferably, the HALS compound is a 2,2,6,6-tetraalkylpiperidine compound, salt, or metal complex, and the UV light absorber is a tris-aryl-2-triazine of formula where X, Y, and Z are each aromatic carbocyclic groups, and at least one of the aromatic groups has a hydroxy group ortho to the point of attachment to the triazine ring. Each of R 1 to R 9 is hydrogen, hydroxy, alkyl, alkoxy, sulfonic, carboxy, halo, haloalkyl, or acylamino. Each of the UV light absorbers and HALS compound are used in an amount of from about 0.01 to 5 percent by weight, but only formulations having equal amounts of UV light absorber and HALS compound are exemplified. The compositions are effective in stabilizing the polymeric material, which does not begin to lose gloss or turn yellow until after about 1,000 to 2,400 hours of exposure to UV light. Thus, a need still remains for improved articles, and compositions and methods of use and preparation thereof, that stabilize polymeric materials and provide protection from exposure to UV light for extended periods of time. The present invention provides such compositions, articles and methods.

DETAILED DESCRIPTION OF THE INVENTION An improved class of HALS compounds has now been discovered that provides substantially similar or superior UV light protection over a longer period of time compared to conventional HALS compounds. The HALS compounds of the present invention are based on the reaction of a lactam with the carbonyl group of a carbonyl compound. The HALS compounds of the present invention include compounds where the functional component of the HALS compound, a piperidin-4-ol or 4 aminopiperidine group, is anchored to the terminus of a hydrocarbon chain by an ester functionality or an amide functionality and wherein the other end of the hydrocarbon chain terminates with an amide linkage that is not a HALS functionality. These may be referred to as "ester/amide HALS compounds" and "amide/amide HALS compounds." Alternatively, both ends of the hydrocarbon chain can terminate with the piperidin-4-ol or 4 aminopiperidine group. In this embodiment, the HALS molecule is anchored to one terminus of the hydrocarbon chain by an ester functionality and to the other terminus by a urethane functionality. These may be referred to as "ester/urethane HALS compounds." Furthermore, the HALS molecule may be anchored to one terminus of the hydrocarbon chain by an amide functionality and to the other terminus by a urea functionality. These may be referred to as "amide/urea HALS compounds." In yet another series of compounds, the piperidin-4-ol or 4 aminopiperidine group is bonded by an ester linkage to one terminus of the hydrocarbon chain and by an oxamate linkage at the other terminus of the hydrocarbon chain to provide "ester/oxamate HALS compounds," or the piperidin-4-ol or 4 aminopiperidine group is bonded by an amide linkage to one terminus of the hydrocarbon chain and by an oxamide linkage at the other terminus of the hydrocarbon chain to provide "amide/oxamide HALS compounds." Monomeric HALS Compounds of the Invention These HALS compounds are represented by the general formula (I) RZ-CO-CR a R b -(-CR c R d -) n -NH-(Y) m -CO-A (I) wherein n is an integer from 1 to 15, preferably 4 to 11; m is either 0 or 1; R\ R b , R c , and R d , are each a hydrogen or a hydrocarbyl group; Y is CO-(CR e R f ) p , wherein R and R f are each a hydrogen or hydrocarbyl group and p is zero or an integer from 1 to 20 or CO-C 6 H 4 -, and the substimtion pattern on the phenylene group, i.e. , -C 6 H 4 -, may be an ortho, meta, or para substimtion pattern, in addition one or more of the hydrogens of the phenylene group may be substimted by a hydrocarbyl group or other functional group commonly found in organic molecules; Z is -O- or NG, wherein G is H, C,-C, 2 alkyl or the radical R; wherein the radical R represents: wherein R 1 represents hydrogen, C,-C lg alkyl, O, OH, CH 2 CN, C,-C, 8 alkoxy, C,-C, 8 hydroxy alkoxy, C 5 -C, 2 cycloalkoxy, C 5 -C, 2 hydroxy cycloalkoxy, C 3 -C 6 alkenyl, C,-C 18 alkynyl, C 7 -C 9 phenylalkyl, unsubstituted or substimted on the phenyl with 1, 2 or 3 C,- C 4 alkyls, or an aliphatic C,-C 8 acyl; R 2 is hydrogen, C,-C 8 alkyl, or benzyl; R 3 , R 4 , R 5 , and R 6 are each a hydrogen, C,-C 8 alkyl, benzyl or phenethyl, or two geminal R moieties, which together with the carbon to which they are attached, form a C 5 -C 10 cycloalkyl; and A is either ZR or a hydrocarbyl group. The term "hydrocarbyl," as used herein, is a monovalent hydrocarbon group in which the valency is derived by extraction of a hydrogen from a carbon. Hydrocarbyl includes, for example, aliphatics (straight and branched chain), cycloaliphatics, aromatics and mixed character groups (e.g. , aralkyl and alkaryl). Hydrocarbyl also includes groups with internal unsaturation and activated unsaturation. More specifically, hydrocarbyl includes, but is not limited to, alkyl, cycloalkyl, aryl, aralkyl, alkaryl, alkenyl, cycloalkenyl, and alkynyl, typically having from about 1 to 24 carbon atoms, preferably having from about 1 to 12 carbon atoms. A hydrocarbyl may contain one or more carbonyl groups (which is/are included in the carbon count) and/or a heteroatom or heteroatoms (such as at least one oxygen, nitrogen, sulfur, or silicon) in the chain or ring. In addition, a hydrocarbyl may have one or more of the hydrogens of the hydrocarbon group replaced by a functional group commonly found in organic molecules. The phrase "functional group commonly found in organic molecules" means non-hydrocarbyl groups that are typically found in organic molecules including, but not limited to, halides, cyano groups, amino groups, thiol groups, carboxy late groups, hydroxyl groups, sulfonate groups, nitroso groups, nitro groups, and the like. The term "hydrocarbylene" in the context of the present invention is a divalent hydrocarbon group in which both valencies derive by abstraction of hydrogens from carbon atoms. Included within the definition of hydrocarbylene are the same groups as indicated above for hydrocarbyl and functional hydrocarbyl with, of course, the extra valency (for example, alkylene, alkenylene, arylene, etc.). In a preferred embodiment of the invention, R 1 is H, C,-C 4 alkyl,C,-C, 8 alkoxy, C 5 -C, 2 cycloalkoxy, O, or OH; R 2 is H, or C,-C 4 alkyl; R 3 , R 4 , R 5 , and R 6 are H or C,-C 4 alkyl; R\ R b , R c , and R d , are each a hydrogen, aromatic, or C,-C 4 alkyl; and n is from about 2 to 10. In a more preferred embodiment, R represents the 2,2,6,6- tetramethylpiperidine radical (i.e. , R\ R 4 , R 5 , R 6 are methyl and R 2 is hydrogen) or 1,2,2,6,6-pentamethylpiperidine radical (i.e. , R 2 , R 3 , R\ R 5 , and R 6 are methyl); R a , R b , R c , and R d are each a hydrogen; Z is -O-; m is 0 or 1; and n is 4 to 10. Synthesis of Monomeric HALS Compounds The HALS compounds of the formula (I) are typically prepared by the reaction of a multi-functional carbonyl compound with a 4-piperidin-ol or a 4- aminopiperidine moiety. The multi-functional carbonyl compound has the general structure: DO-CO-CR a R b -(-CR c R d -) n -NH-(Y) m -CO-B wherein n is an integer from 1 to 15, preferably 4 to 11; m is either 0 or 1; R\ R b , R c and R d , are each a hydrogen or a hydrocarbyl group; Y is CO-(CR e R , ) p , wherein R e and R f are each a hydrogen or hydrocarbyl group, and p is zero or an integer from about 1 to 20 or CO-C 6 H 4 -, and the substimtion pattern on the phenylene group, i.e. , -C 6 H 4 -, is an ortho, meta, or para substitution pattern, in addition one or more of the hydrogens of the phenylene group may be substimted by a hydrocarbyl group or a functional group commonly found in organic molecules; D is a hydrocarbyl group; and B is either OD or D; and reacting the carbonyl compound with a 1 -substimted piperidin-4-ol or 4- aminopiperidine of general structure: wherein Z is OH or NHG, wherein G is H or C,-C, 2 alkyl or the radical R (wherein R is defined above); and R 1 is hydrogen, C,-C l8 alkyl, O, OH, CH 2 CN, C,-C 18 alkoxy, C,-C 18 hydroxyalkoxy, C 5 -C 12 cycloalkoxy, C 5 -C 12 hydrocycloalkoxy, C 3 -C 6 alkenyl, C,-C 18 alkynyl, C 7 -C 9 phenylalkyl, unsubstituted or substituted on the phenyl with 1, 2 or 3 C,-C 4 alkyls, or an aliphatic C,-C 8 acyl; R 2 is hydrogen, C,-C 8 alkyl, or benzyl; R 3 , R 4 , R 5 , and R 6 are each a hydrogen, C,-C 8 alkyl, benzyl or phenethyl, or two geminal R moieties, which together with the carbon to which they are attached, to form a C 5 -C 10 cycloalkyl. The reaction between the multi-functional carbonyl compound and the 4- piperidin-ol or 4-aminopiperidine moiety is conducted for a sufficient time for the compound of formula (I) to be formed. The phrase "conducted for a sufficient time for the compound of [a given formula] to be formed" means that after the reactants are combined they are allowed to react for sufficient time to produce a detectable amount of the desired compound, i.e. , the compound of a given formula. By "detectable amount" of a compound is meant an amount of the compound that can be detected by any means readily available to those of ordinary skill in the art. Means for detecting the formation of a compound in a reaction mixture include, but are not limited to, thin layer chromatography (TLC), high performance liquid chromatography (HPLC), gas chromatography (GC), column chromatography, nuclear magnetic resonance spectroscopy (NMR), infra-red (IR) spectroscopy, ultra-violet (UV) or visible (VIS) spectroscopy, and wet-chemical analysis, for example. The length of time for the desired compound to be produced is dependent on a number of variables and, thus, cannot be generalized. For example, the reaction time is dependent on the temperature, the pressure, the specific reactants (i.e. , the multi-functional carbonyl compound and the 1 -substimted piperidin-4- ol or 4-aminopiperidine), and the solvent and catalyst, if present. Acceptable parameters that produce the desired product, however, may be readily determined by those of ordinary skill in the art without undue experimentation. The reaction may be carried out in the absence of a solvent or in the presence of a solvent. When the reaction is carried out in the absence of a solvent either the multi-functional carbonyl compound or the 4-piperidin-ol or 4-aminopiperidine may be present in an excess and employed as the reaction medium. Alternatively, the multifunctional carbonyl compound and 4-piperidin-ol or 4-aminopiperidine can be present in a stoichiometric amount. The multi-functional carbonyl compound and 4-piperidin-ol or 4- aminopiperidine may be present in a melt. Preferably, the reaction is carried out in an organic solvent. Any solvent compatible with the reagents may be used. Preferred solvents for use in the method of the invention include, but are not limited to, hydrocarbon solvents such as a samrated alkanes; benzene; toluene; xylenes; halogenated hydrocarbons; ethers such as ethyl ether; cyclic ethers such as tetrahydrofuran and dioxane; amides such as dime thy lformamide; sulfoxides such as dimethylsulfoxide; ketones such as 2-butanone or methyl isobutyl ketone; and the like; or combinations thereof. The more preferred solvents include toluene, benzene, and xylenes. When the reaction is carried out in a solvent the concentration of the multi- functional carbonyl in the organic solvent is generally from about 0.025 M to 2.5 M, preferably from about 0.125 M to 2 M, and more preferably from about 0.25 M to 1.35 M. The molar ratio of the 1 -substimted piperidin-4-ol or 4-aminopiperidine to the multifunctional carbonyl compound is between about 20: 1 and 1:5, preferably between about 10: 1 and 1:3, and more preferably between about 5: 1 and 1:5. The reaction of the multi-functional carbonyl compound and 4-piperidin-ol or 4-aminopiperidine produces an alcohol of structure DOH. Preferably, the alcohol is removed from the reaction mixture as it is formed to help drive the reaction to completion. The alcohol may be removed by any means available to those of ordinary skill in the art such as distillation and or azeotropic distillation. Preferably, the reaction is conducted in the presence of a catalyst. The optional catalyst may be a basic or an acidic catalyst. The phrase "base catalyst" means any compound that can abstract a proton. Base catalysts suitable for the invention include, but are not limited to, alkoxide ions; hydroxide ion; amide ion; and amines such as triethylamine, DBU (1,8-diazabicyclo [5.4.0] undec-7-ene), or DBN (1,5-diazabicyclo [4.3.0] non-5-ene). When an amine is used as the base, it is preferred that the amine is a tertiary amine. The phrase "acid catalyst" means any inorganic or organic acid with at least one acidic proton or a Lewis acid. The organic acids include any organic compound that contains at least one acidic functional group, including one or more of RCO 2 H, RSO 3 H, RSO 2 H, RSH, ROH, RPO 3 H, RPO 2 H, wherein R is a hydrocarbyl group. Preferred protic acids include HC1, HBr, HI, HNO 3 , HNO 2 , H 2 S, H 2 SO 4 , H 3 PO 4 , H 2 CO 3 , acetic acid, formic acid, propionic acid, butanoic acid, benzoic acid, phthalic acid, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, methanesulfonic acid, and p- toluenesulfonic acid, or mixmres thereof. Lewis acids suitable for the method of the invention include, but are not limited to, aluminum halides, alkylaluminum halides, boron halides, dialkyl tin oxides and derivatives thereof, tin halides, titanium halides, lead halides, zinc halides, iron halides, gallium halides, arsenic halide, copper halides, cadmium halides, mercury halides, antimony halides, and the like.

The acid or base catalyst may also be a solid supported catalyst such as amberlyst catalysts. The catalyst is typically added in an amount of less than about 30 mole percent based on the molar quantity of the multi-functional carbonyl compound, preferably less than about 20 mole percent based on the molar quantity of the multifunctional carbonyl compound, more preferably less than about 10 mole percent based on the molar quantity of the multi-functional carbonyl compound, and most preferably less than about 5 mole percent by weight based on the weight of the multi-functional carbonyl compound. The preferred base catalyst for use in the method of the invention is methoxide ion. The preferred acid catalyst is a Lewis acid. The preferred Lewis acid is 1 ,3-diacetoxy-l , 1,3,3- tetrabutyldistannoxane. Preferably, the reaction is allowed to proceed for a time that is less than about 20 hours and more preferably less than about 10 hours. Typically, the reaction temperature is from about room temperature to 150°C, for example, up to the boiling point of the solvent. Typically, the reactions are run at atmospheric pressure. Representative reaction conditions for forming the compound of formula (I) are provided in the examples. After the compound of formula (I) is formed, it is recovered from the reaction mixmre by any means available to those of ordinary skill in the art. Methods for recovering compounds from a reaction mixmre include, but are not limited to, chromatography, recrystallization, distillation, extraction, and the like. More than one method may be used to recover a compound from the reaction mixmre. In a preferred embodiment, the substimted 4-piperidin-4-ol is 1,2,2,6,6- pentamethyl-4-piperidinol or 2,2,6,6-tetramethyl-4-piperidinol and the multi-functional carbonyl compound is methyl 6-(methoxycarbonylamino)hexanoate, butyl 6- (butoxycarbonylamino) undecanoate, methyl 6-(butoxycarbonylamino)undecanoate, butyl 6-(methoxycarbonylamino)undecanoate, or methyl 6- (methoxycarbonylamino)undecanoate. The multi-functional carbonyl compounds can be prepared by any method available to those of ordinary skill in the art. In one embodiment, the multi-functional carbonyl compound is prepared by reacting a lactam with a carbonyl compound. For example, the multi-functional carbonyl compound can be prepared by the base catalyzed reaction of a lactam and a carbonyl compound according to the method disclosed in U.S. Patent No. 5,300,678, the contents of which are expressly incoφorated herein by reference thereto. Any lactam may be used according to the method of the invention. Preferably the size of the lactam ring is from about 4 to 13 atoms. More preferably the lactam is caprolactam or laurolactam. The carbonyl compound must include at least one reactive carbonyl group. "Reactive carbonyl group" means any carbonyl group that is attached to a good leaving group and, thus, is activated towards nucleophilic acyl substimtion. The reactive carbonyl group may be, for example, an ester or acid chloride. Preferably the carbonyl compound is an ester. More preferred carbonyl compounds include dialkyl carbonates, dialkyl oxalates, dialkyl diesters, or alkyl esters. The general structure of the carbonyl compound is O II O— (Y)πr- C χ E wherein m is either 0 or 1, Q is a good leaving group, such as chloride or OD, wherein D is a hydrocarbyl group, preferably methyl, and B is Q or a hydrocarbyl group and Y is CO-(CR e R f ) p , wherein R e and R f are each a hydrogen or hydrocarbyl group and p is zero or an integer from about 1 to 20 or CO-C 6 H 4 -, and the substimtion pattern on the phenylene group, i.e. , -C 6 H 4 -, may be an ortho, meta, or para substimtion pattern, in addition one or more of the hydrogens of the phenylene group may be substimted by a hydrocarbyl group or other functional group commonly found in organic molecules. When the carbonyl compound is a dialkyl carbonate, the resulting multi- functional carbonyl compound is a hydrocarbon chain that terminates on one end with an ester functionality and the other end with a urethane functionality. When the carbonyl compound is a dialkyl oxalate, the resulting multi-functional carbonyl compound is a hydrocarbon chain that terminates on one end with an ester functionality and the other end with an oxamate functionality. When the carbonyl compound is a dialkyl ester, the resulting multi-functional carbonyl compound is a hydrocarbon chain that includes an amide linkage and terminates on each end with an ester functionality. When the carbonyl compound is an alkyl ester, the resulting multi-functional carbonyl compound is a hydrocarbon chain that terminates on one end with an ester functionality and the other end with an amide functionality. The reaction of the lactam with the carbonyl compound can be conducted in a solvent or in the absence of a solvent. When the reaction is conducted in the absence of a solvent, excess carbonyl compound may be employed as the reaction medium and, thus, the carbonyl compound may be present in an excess compared to the lactam. The lactam, however, may also be present in an excess and employed as the reaction medium. Alternatively, the lactam and carbonyl compound can be present in a stoichiometric amount. The lactam and carbonyl compound may be present in a melt. When the reaction is conducted in the absence of a solvent, the excess carbonyl compound or lactam may be recovered by, for example, distillation and reused. An advantage of not using a solvent is that the problems associated with disposal of waste solvents are avoided. In another embodiment one or more different lactams are reacted with one or more different carbonyl compounds. For example, two lactam molecules can be reacted with 1 molecule of carbonyl compound. Solvents suitable for the method of the invention include, but are not limited to, hydrocarbon solvents such as a samrated alkane; benzene; toluene; xylenes; halogenated hydrocarbons; ethers such as ethyl ether; cyclic ethers such as tetrahydrofuran and dioxane; amides such as dimethylformamide; sulfoxides such as dimethylsulfoxide; ketones such as 2-butanone or methyl isobutyl ketone; alcohols; and the like; or mixtures thereof. When the reaction is carried out in a solvent the concentration of the lactam in the solvent is from about 0.025 M to 10 M, preferably from about 0.375 M to 6 M, and more preferably from about 0.25 M to 4 M. The mole ratio of lactam to carbonyl compound is typically from about 1: 10 to 5: 1, preferably from about 1:5 to 2: 1, and more preferably from about 1:2.5 to 1.5: 1. The reaction is allowed to proceed for a sufficient time to form a detectable amount of the multi-functional carbonyl compound. In general the reaction time is less than about 12 hours. Typically, the reaction temperamre is from about room temperamre to 150°C, for example, up to the boiling point of the solvent, when a solvent is used. The reaction is typically conducted at room temperamre. The present invention also provides an improved method for preparing the multi-functional carbonyl compound. According to the method of the invention the lactam and a carbonyl compound are reacted in the presence of an acid catalyst, preferably a Lewis acid catalyst. Any Lewis acid catalyst can be used according to the method of the invention. For example, any of the above-mentioned Lewis acid catalysts may be used. Preferably the Lewis acid catalyst is titanium (IV) isopropoxide. Lewis acids are a preferred catalyst since they can be easily removed from the reaction mixmre. For example, many Lewis acids, such as tetraorganotitanates, can be readily hydrolyzed with a stoichometric amount of water, leading to a highly insoluble titanium dioxide that can easily be removed from the reaction mixmre by filtration. Other Lewis acids, such as, for example, boron trifluoride etherate, are sufficiently volatile that they can easily be removed from the reaction mixmre by distillation. Thus, using a Lewis acid can advantageously avoid having to extract the reaction mixmre with an aqueous solvent to remove the catalyst. By avoiding an extraction step to remove the catalyst, the method of the invention generates less aqueous waste that ultimately has to be disposed of. In another improved method of the invention, the lactam and carbonyl compound are allowed to react with an alkoxide anion as a basic catalyst, preferably methoxide anion. The reaction, however, is conducted at a temperamre of less than about 20 °C, preferably less than about 19 °C, and more preferably less than about 15°C. The lactam and carbonyl compound are allowed to react for less than about 5 hours, preferably less than about 2 hours, and more preferably less than about 1 hour. Conducting the reaction at a low temperamre is preferred since temperatures can be kept below the flash point of many reagents and, thus, such low temperamre reactions can be significantly safer. For example, dimethyl carbonate (which is a common carbonyl compound for use in the method of the invention) has a flash point of 19°C. By running the reaction at a temperamre below 19 °C, i.e. , below the flash point, the method is significantly safer than prior art methods that require higher temperatures. When the multi-functional carbonyl compound is formed, it can be recovered from the reaction mixmre before it is reacted with the 1-substimted piperidin-4- ol or 4-aminopiperidine to form the HALS of the invention. The multi-functional carbonyl compound may be recovered by any means available to those of ordinary skill in the art. Optionally, the multi-functional carbonyl compound is not recovered from the reaction mixmre and instead the 1-substimted piperidin-4-ol or 4-aminopiperidine is added to the reaction mixmre after a detectable amount of the multi-functional carbonyl compound is formed. The 1-substimted piperidin-4-ol or 4-aminopiperidine and the multi-functional carbonyl compound can then react to form the HALS of the invention. In a preferred method, the compound of formula (I) is prepared by reacting the lactam, carbonyl compound, and 1-substimted piperidin-4-ol or 4-aminopiperidine in a single step. The lactam, the carbonyl compound, and the 1-substimted piperidin-4-ol or 4-aminopiperidine are combined and allowed to react at the same time, rather than reacting the lactam and carbonyl compound to form the multi-functional carbonyl compound in a first step and then, in a subsequent step, reacting the multi-functional carbonyl compound with the 1-substimted piperidin-4-ol or 4-aminopiperidine. The lactam, the carbonyl compound, and the 1-substimted piperidin-4-ol or 4-aminopiperidine are combined in a reaction vessel and allowed to react for sufficient time to form a detectable amount of the HALS of formula (I). The ratio of lactam to carbonyl compound in this embodiment of the method is from about 2:1 to 1:4, preferably from about 1:1 to 1:2; and the ratio of lactam to 1-substimted piperidin-4-ol or 4-aminopiperidine is from about 1 :1 to 1:6, preferably from about 1:2 to 1:4. The single step reaction can be conducted in a solvent or in the absence of a solvent. When a solvent is used, any solvent that is compatible with the reagents may be used. Representative solvents include, but are not limited to, those solvents described above for the reaction of a 1-substimted piperidin-4-ol or 4-aminopiperidine with a multifunctional carbonyl compound. Preferably, the reaction in this embodiment is carried out in the presence of a solvent. When a solvent is employed, the concentration of lactam is typically from about 0.025 M to 10 M, preferably from about 0.325 M to 6 M, and more preferably from about 0.75 M to 4 M. Preferably, the reaction is carried out in the presence of a catalyst. The same catalysts may be used as were used in the reaction of a 1-substimted piperidin-4-ol or 4-aminopiperidine with a multi-functional carbonyl compound. The catalyst is typically present in an amount of less than about 30 mole percent, preferably less than about 20 mole percent, and more preferably less than about 10 mole percent, and most preferably less than 5 mole percent, relative to the amount of carbonyl compound. Preferably, the carbonyl compound is an ester, i.e. , Q=OD, so that the reaction produces an alcohol of structure HOD. Preferably, the alcohol is removed from the reaction mixmre as it is formed to drive the reaction to completion. The alcohol may be removed by any means available to those of ordinary skill in the art, such as distillation and/or azeo tropic distillation. Preferably, the reaction time is less than about 20 hours and more preferably less than about 10 hours. Typically, the reaction temperamre is between about room temperamre and 250 °C. Typically, the reactions are run at atmospheric pressure. Representative reaction conditions for forming the HALS of formula (I) by the single step process are provided in the examples. When the HALS of formula (I) is formed it may be recovered from the reaction mixmre by any means available to those of ordinary skill in the art.

Preferably, the light-stabilized polymeric material is formed from a polyolefin homopolymer or copolymer, and more preferably a homopolymer or copolymer of polyethylene or polypropylene. The novel HALS of the present invention can also be employed in multilayer systems. In such systems, a polymer composition having from about 0.1 to 20 percent by weight and preferably having a relatively high content of the novel HALS of the invention, for example, from about 5 to 15 percent by weight, is applied in a thin film (typically between about 5 to 500 μm and preferably from about 10 to 100 μm thick) to a shaped article made from a polymer containing little or no ultraviolet stabilizers. Such composition may be applied at the same time as the shaping of the base strucmre, for example by coextrusion. Alternatively, application can also be made to the ready-formed base strucmre, for example by lamination with a film or by coating with a solution. The outer layer or layers of the finished article have the function of a UV filter, which protects the interior of the article from UV light. The outer layer preferably contains about 0.1 to 20 percent, preferably about 1 to 15 percent and more preferably about 2 to 10 percent by weight of the outer layer composition, of at least one of the HALS of the present invention. British Patent Appn. No. 2,290,745 describes a number of methods that have been developed to concentrate UV absorbers near or at the surface of polymeric materials. These include surface impregnation (see U.S. Patent Nos. 3,309,220, 3,043,709, 4,481,664 and 4,937,026) and coating a plastic article with solutions containing thermoplastic resins and UV absorbers (see U.S. Patent Nos. 4,668,588 and 4,353,965). Both techniques, however, suffer from drawbacks such as requiring additional processing steps (i.e. , applying, drying or curing), and encounter difficulties associated with the handling of large processed articles. An additional drawback, particularly relevant to polycarbonate sheet production, is the detrimental effect such post addition treatment would have on the surface of the polymeric substrate. As described in the U.S. Pat. No. 5,445,872, application of surface layers via coextrusion takes place in a known manner with known coextrusion equipment as taught in U.S. Pat. Nos. 3,487,505 and 3,557, 265, which is a preferred way to incoφorate HALS compounds onto the surface of a polymeric article according to the present invention. Coextrusion is a well recognized method of producing laminated thermoplastic materials by simultaneously extruding various numbers of layers which form a single composite material. U.S. Patent No. 4,540,623 describes coextruded materials of at least forty layers. Other methods known to those of ordinary skill in the art produce as few as two or three different layers. In one embodiment, the invention relates to thermoplastic articles coated with a thermoplastic layer about 0.1 to 10 mil (0.00254 mm to 0.254 mm) thick, preferable about 0.1 to 5 mil (0.00254 mm to 0.127 mm) thick, in which the layer contains between about 0.1 % to 20% by weight of one or more of the HALS of the invention. Preferred concentrations are from about 2% to 15% by weight; most preferred are concentrations from about 5% to 10% by weight. The HALS of the instant invention may be incoφorated into the thermoplastics of the surface layer by standard methods, such as dry mixing the additives with a granular resin prior to extruding. The HALS layer may be applied to one or more sides of a thermoplastic article according to the present invention. Laminated thermoplastic articles corresponding to the present invention which contain additional layers such as a water resistant layer, as found in U.S. Pat. No. 4,992,322, are also within the scope of the present invention. The core layer and the coating layer may be of the same thermoplastic resin or different. Examples of thermoplastic resins include thermoplastic polyesters, polyester carbonates, polyphenylene oxide, polyvinyl chloride, polypropylene, polypropylene, polyethylene, polyacrylates, polymethacrylates and copolymers and blends such as styrene and acrylonitrile on polybutadiene and styrene with maleic anhydride; and blends thereof. The polymers stabilized in this way are notable for high weathering resistance, especially for high resistance to UV light. This enables them to substantially retain their mechanical properties and their color and gloss for a long time even when used in harsh environments. Coating Stabilizers Including HALS Compounds and Preparation of the Same In another embodiment of the present invention, novel mixmres comprising at least one HALS of the invention can be used as stabilizers for coatings, for example for paints. Of particular interest are coatings and paints for the automobile industry. "Coating" means a free flowing composition that can be applied to the surface of an article in a thin film that then hardens to form a substantially solid surface on the article. Typically, the coating provides an interface between the article and the environment. Such novel coating compositions comprise from about 0.01 to 20 percent, preferably from about 0.01 to 10 percent and more preferably from about 0.02 to 5 percent by weight of one or more of the HALS of the present invention. The coating may be applied to the surface of the article in one or more than one layer to provide a multilayered system. In multilayer systems, the concentration of the novel HALS compounds in the outer layer can be relatively high, for example from about 0.01 to 20 percent, preferably from about 0.01 to 10 percent, and more preferably from about 0.02 to 5 percent by weight. The use of the novel stabilizer in coatings is accompanied by the additional advantage that it inhibits or prevents delamination, i.e. , the flaking -off of the coating from the substrate. This advantage is particularly important in the case of metallic substrates, including multilayer systems on metallic substrates, which have such flaking tendencies. The coatings typically include a binder that suspends pigments and other additives in the coating and allows attachment of the coating to the substrate. The binder can in principle be any binder which is customary in industry, for example those described in Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 368-426, VCH, Weinheim, 1991, which is incoφorated herein by reference. In general, it is a film-forming binder based on a thermoplastic or thermosetting resin, predominantly on a thermosetting resin. Examples thereof are alkyd, acrylic, polyester, phenolic, melamine, epoxy, and polyurethane resins, and mixmres thereof. Such binders can be a cold-curable or hot-curable binder. Further, in some systems it may be advantageous to add a curing catalyst to such systems. Suitable catalysts which accelerate curing of the binder are described, for example, in Ullmann's Encyclopedia of Industrial Chemistry, Vol. A 18, p. 469, VCH Nerlagsgesellschaft, Weinheim, 1991, which is incoφorated herein by reference. Preferred binders include those which comprise a functional acrylate resin and a crosslinking agent. A wide variety of binders may be employed in such coating systems. Examples of suitable coating compositions containing specific binders, include but are not limited to: 1. paints based on cold- or hot-cross-linkable alkyd, acrylate, polyester, epoxy or melamine resins, or mixmres of such resins, if desired with addition of a curing catalyst; 2. two-component polyurethane paints based on hydroxyl-containing acrylate, polyester or polyether resins and aliphatic or aromatic isocyanates, isocyanurates or poly isocyanates; or mixmres thereof; 3. one-component polyurethane paints based on blocked isocyanates, isocyanurates or polyisocyanates which are deblocked during baking;or mixmres thereof; 4. two-component paints based on (poly)ketimines and aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates; or mixmres thereof; 5. two-component paints based on (poly)ketimines and an unsaturated acrylate resin or a polyacetoacetate resin or a methacrylamidoglycolate methyl ester; or mixmres thereof; 6. two-component paints based on carboxyl- or amino-containing polyacrylates and polyepoxides; or mixmres thereof; 7. two-component paints based on acrylate resins containing anhydride groups and on a polyhydroxy or polyamino component; or mixmres thereof; 8. two-component paints based on (poly)oxazolines and acrylate resins containing anhydride groups, or unsaturated acrylate resins, or aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates; or mixmres thereof; 9. two-component paints based on unsaturated polyacrylates and polymalonates; or mixmres thereof; 10. thermoplastic polyacrylate paints based on thermoplastic acrylate resins or externally crosslinking acrylate resins in combination with etherified melamine resins; or mixmres thereof; 11. paint systems based on siloxane-modified or fluorine-modified acrylate resins or mixmres thereof; . In addition to the binder and novel HALS of the present invention, the coating composition according to the invention may further comprise one or more additional additives, such as an antioxidant or additional ultraviolet light absorber or stabilizer. Additional additives include, but are not limited to, those specifically listed above. The additional additive is employed in coating compositions in an amount of from about 0.01 to 5 percent, preferably from about 0.02 to 2 percent by weight. In addition, well known to those of ordinary skill in the art to be suitable for coating compositions the coating composition can also comprise further components including, but not limited to, solvents, pigments, dyes, plasticizers, stabilizers, thixo tropic agents, drying catalysts and/or leveling agents, or combinations thereof. Examples of possible components are those described in Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 429-471, VCH, Weinheim 1991, which is incoφorated herein by reference. Exemplary drying catalysts or curing catalysts are, for example, organometallic compounds, amines, amino-containing resins and/or phosphines. Examples of organometallic compounds are metal carboxy lates, especially those of the metals Pb, Mn, Co, Zn, Zr or Cu, or metal chelates, especially those of the metal Al, Ti or Zr, or organometallic compounds such as organotin compounds, for example, and mixmres thereof. Examples of metal carboxylates are the stearates of Pb, Mn or Zn, the octoates of Co, Zn or Cu, the naphthenates of Mn and Co or the corresponding linoleates, resinates or tallates, and mixmres thereof. Examples of metal chelates are the aluminum, titanium, or zirconium chelates of acetylacetone, ethyl acetylacetate, salicylaldehyde, salicylaldoxime, o- hydroxyacetophenone, or ethyl trifluoroacetylacetate, and the alkoxides of these metals, and mixmres thereof. Examples of organotin compounds are dibutyltin oxide, dibutyltin dilaurate or dibutyltin dioctoate, and mixmres thereof. Examples of amines are, in particular, tertiary amines, for example tributylamine, triethanolamine, N-methyldiethanolamine, N-dimethylethanolamine, N- ethylmoφholine, N-methylmoφholine or diazabicyclooctane (triethylenediamine) and salts thereof, and mixmres thereof. Further examples are quaternary ammonium salts, for example trimethylbenzylammonium chloride. Amino-containing resins are simultaneously a binder and a curing catalyst. Examples thereof are amino-containing acrylate copolymers. The curing catalyst used can also be a phosphine, for example tr iphenylphosphine . The novel coating compositions can also be radiation-curable coating compositions. In this case, the binder includes monomeric or oligomeric compounds containing ethylenically unsaturated bonds, which after application are cured by actinic radiation, i.e. , converted into a crosslinked, high molecular weight form. Where the system is UV-curable, it generally contains a photoinitiator as well. Corresponding systems are described in the above-mentioned publication Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pages 451-453, which is incoφorated herein by reference. In radiation-curable coating compositions, the novel stabilizers can also be employed with or without additional UV light stabilizers, including sterically hindered amines. The coating compositions according to the invention can be applied to any desired substrates, for example to metal, wood, plastic, or ceramic materials. They are preferably used as topcoats in the finishing of automobiles. If the topcoat comprises two layers, of which the lower layer is pigmented and the upper layer is not pigmented, the novel coating composition can be used for either the upper or the lower layer or for both layers, but preferably for the upper layer. The novel coating compositions can be applied to the substrates by any conventional methods available to those or ordinary skill in the art, for example by brushing, spraying, pouring, dipping, or electrophoresis; see also Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 491-500, which is incoφorated herein by reference. Depending on the binder system, the coatings can be cured at room temperamre or may require heating. The coatings are preferably cured at a temperamre of from about 50 °C to 150°C, and in the case of powder coatings, even at higher temperatures. The coatings obtained in accordance with the invention generally have excellent resistance to the damaging effects of light, oxygen, and heat. In particular, the presently claimed coatings provide good light stability and weathering resistance. The invention therefore encompasses coatings, in particular a paint, which has been stabilized against the damaging effects of light, oxygen, and/or heat by a content of at least one of the HALS of the present invention incoφorated into or onto an article. The paint may be a pigmented mono-coat which includes a film-forming binder and an organic pigment or dye, an inorganic pigment, a metallic pigment, or a mixmre thereof. The paint may also be a composition which comprises a primer in adhesion to a metal or plastic substrate; a pigmented base coat that is in adhesion to the primer, and which comprises a film-forming binder and an organic pigment or dye, an inorganic pigment, a metallic pigment, or a mixmre thereof; and a clear top coat that is in adhesion to the base coat, and which comprises a film-forming binder and optionally a transparent pigment. The paint is preferably a topcoat for automobiles. The invention furthermore relates to a process for stabilizing a coating based on organic polymers against damage by light, oxygen, and/or heat, which comprises mixing with the coating composition a mixmre comprising one or more HALS of the present invention, as well as the use of mixmres comprising the one or more HALS of the present invention in coating compositions as stabilizers against damage by light, oxygen, and/or heat. The coating compositions can comprise an organic solvent or solvent mixmre in which the binder is soluble. The coating composition can otherwise be an aqueous solution or dispersion. The carrier can also be a mixmre of organic solvent and water. The coating composition may be a high-solids paint or can be solvent-free (e.g. , a powder coating material). The pigments can be inorganic, organic or metallic pigments. The novel coating compositions preferably contain no pigments and preferably are used in clearcoat compositions. Likewise preferred is the use of the coating composition as a topcoat for applications in the automobile industry, especially as a pigmented or unpigmented topcoat of the paint finish. Its use for underlying coats, however, is also possible.

The recovered N-(2-hydroxyethyl)-2,2,6,6-tetramethyl-4- piperidinol had a melting point of 179- 183 °C (literature melting point 182°C, DE 2,352,658). The synthesis of Compounds A, B, C and D are described below. Synthesis of Compound A: To a 300 mL 3-necked round bottom flask equipped with a mechanical stirrer, a ground glass stopper and a condenser fitted with an argon inlet and outlet to a bubbler was charged 10 g (88 mmol) of caprolactam, 10.5 g (117 mmol) of dimethylcarbonate, 5.23 g (96.8 mmol) of sodium methoxide, and 100 mL of methanol. The mixmre was heated at reflux for 24 hours, then cooled to room temperamre. 7.3 g (121 mmol) of glacial acetic acid was added and the methanol removed by rotary evaporation. The residue was dissolved in 100 mL of methylene chloride and the organic layer extracted with water to remove unreacted caprolactam. Solvent removal by rotary evaporation, followed by further solvent removal in vacuo (< 1mm) at 95 C gave 5.23 g (29%) of compound A as a nearly colorless oil. The strucmre of compound A was established by NMR. l H NMR (CDCI 3 ): δ 4.63 (br s, 1 H, NH); 3.68 (s, 3H, CH 3 - OCO); 3.66 (s, 3H, CH 3 -OCO); 3.17 (br dt, 2H, -CH 2 -NH-); 2.31 (t, 2H, -CH 2 COO); 1.65-1.21 (in, 6H, CH 2 (CH 2 ) 3 CH 2 ).

The mixmre was heated for 64 hours at 110°C. After cooling to room temperamre, 4.9 g (0.10 mol) of glacial acetic acid in 30 g of butanol was added and the mixmre stirred for 5 min. The resulting mixmre was diluted with 500 mL of methylene chloride, washed with water, and dried (MgSO 4 ). Filtration and rotary evaporation gave 19.6 g of a greasy solid. Flash chromatography on 200-400 mesh, 60 A silica gel (0.5% methanol/methylene chloride) gave 7.2 g (25%) of the title compound as a white semi-solid. The strucmre of compound B was established by NMR. 'H NMR (CDCI 3 ): δ 4.61 (br s, 1H, NH); 4.05 (q, 4H, - CH 2 CH 2 -OCO); 3.16 (br dt, 2H, -CH 2 - NH-); 2.28 (t, 2H, -CH 2 COO); 1.65-1.21 (m, 26H, CH 2 (CH 2 ) 9 CH 2 , (CH 2 ) 2 CH 3 ), 0.93 (t, 6H, CH 3 ). Synthesis of Compound C: To a 100-mL round bottom flask equipped with a stir bar was charged 8.45 g (75 mmol) of caprolactam, 8.85 g (75 mmol) of dimethyl oxalate, and 0.16 g (3 mmol) of sodium methoxide. The mixmre was immersed in a 50°C oil bath and heated for 30 min, then cooled over an hour to 35 °C. After stirring at this temperamre for several hours, the mixmre was cooled and allowed to stand overnight at room temperamre. The mixmre was diluted with 125 mL of methylene chloride and washed with water, then washed with samrated sodium chloride solution. Drying over molecular sieves, filtration, and removal of solvent under reduced pressure gave 12.5 g (72% yield) of a light yellow liquid which crystallized to a low melting solid on standing. The strucmre of the material was confirmed by l H NMR analysis. 'H NMR (CDC1 3 ): δ 7.18 (br s, 1H, NH); 3.90 (s, 3H, CH 3 -OCOCO); 3.67 (s, 3H, CH 3 -OCCH 2 ); 3.35 (app q, 2H, -CH 2 -NH-); 2.32 (t, 2H, -CH 2 COO); 1.70-1.30 (m, 6H, CH 2 (CH 2 ) 3 CH 2 ).

The mixmre was immersed in a 185-195°C oil bath and heated for 58 hours. After cooling to 75°C and addition of 0.35 g (6 mmol) of acetic acid the flask was cooled further and residual methyl caprylate (17 g) removed by distillation at 48-67°C/0.8 mm, followed by caprolactam (10 g) at 90-95°C/0.8 mm. The residue was diluted with methylene chloride, washed with water to further remove caprolactam, dried (MgSO_ι), filtered, and evaporated under reduced pressure to give compound D (6.3 g, 38% yield based on unrecovered caprolactam) as a light brown wax. The strucmre of the material was confirmed by 1H NMR analysis. 'H NMR (CDC1 3 ): δ 5.60 (br m, 1 H, G63 NH); 3.62 (s, 3H, CH 3 -OCO); 3.20 (app q, 2H,-CH 2 -NH-); 2.25 (t, 2H, -CH 2 COO-); 2.16 (t, 2H, -CH 2 CONH-); 1.70-1.18 (m, 16H, CH 2 (CH 2 ) 3 CH 2 , CH 2 (CH 2 ) 5 CH 3 ). Synthesis of a Mixmre of Compound E and F: To a 50 mL thick-walled reaction vessel equipped with a magnetic stir bar and a Teflon screw cap was added 10.6 g(53.7 mmol) of laurolactam, 9.83 g (56.4 mmol) of dibutyl carbonate, and 0.58 g (10.7 mmol) of sodium methoxide.

After cooling to room temperamre the mixmre was diluted with 100 mL of methylene chloride and to it was added 0.67 g (11.2 mmol) of acetic acid. Filtration and solvent removal by rotary evaporation, followed by further solvent removal in vacuo (<lmm) at 95 °C gave the product as an off-white paste. Η NMR (CDC1 3 ) indicated the presence of mainly two compounds, E and F, in an approximately 80:20 mole ratio. Flash chromatography (3.5% methanol/methylene chloride) gave pure samples of the two components. Compound E: Η NMR (CDC1 3 ): δ 4.61 (br s, 1H, NH) 4.05 (q, 4H, - CH 2 CH 2 -OCO); 3.16 (br dt, 2H, - CH 2 -NH-); 2.28 (t, 2H, -2H, - CH 2 COO); 1.65-1.21 (m, 26H, CH 2 (CH 2 ) 9 CH 2 , (CH 2 ) 2 CH 3 ), 0.93 (t, 6H, CH 3 ). Compound F: 'H NMR (CDC1 3 ): δ 5.50 (br t, 1H, , -CH 2 NHCOCH 2 ); 4.65 (br s, 1H -CH 2 NHCOOCH 2 4.05 (q, 4H, - CH 2 CH 2 -OCO); 3.21 (dt 2H, -CH 2 NHCOCH 2 -); 3.16 (br dt, 2H, -CH 2 NHCOOCH 2 ); 2.28 (t, 2H, -CH 2 COO); 2.15 (t, 2H, - CH 2 CONH); 1.65-1.21 (M, 26H, CH 2 (CH 2 ) 9 CH 2 , (CH 2 ) 2 CH 3 ), 0.93 (t, H, CH 3 ). The lower temperamre reaction of these reactants gives little or no compound F. Synthesis of a Mixmre of Compound G and H: To a 50 mL thick-walled reaction vessel equipped with a magnetic stir bar and a Teflon screw cap as added 6.06 g (53.7 mmol) of caprolactam, 9.83 g (56.4 mmol) of dibutyl carbonate, and 0.58 g (10.7 mmol) of sodium methoxide. The mixmre was immersed in a 129° C oil bath and heated for 2 hours. After cooling to room temperamre the mixture was diluted with 100 mL of methylene chloride and to it was added 0.67 g (11.2 mmol) of acetic acid. Filtration and solvent removal by rotary evaporation, followed by further solvent removal in vacuo (< 1mm) at 95 °C gave the product as a yellow paste. 'H NMR (CDC1 3 ) indicated the presence of compounds G and H in an approximately 80:20 mole ratio. G H The lower temperamre reaction of these reactants gives little or no compound H. Synthesis of a Mixmre of Compound I and J: To a 25 thick-walled reaction vessel equipped with a magnetic stir bar and a Teflon screw cap was added 2.26 g (20 mmol) of caprolactam, 1.89 g (21 mmol) of dimethyl carbonate, and 54 mg (1.0 mmol) of sodium methoxide. The mixmre was immersed in a 130° C oil bath and heated for l Λ hour. After cooling to room temperature the mixture was diluted with 100 mL of methylene chloride and to it was added 0.67 g (11.2 mmol) of acetic acid. Filtration and solvent removal by rotary evaporation, followed by further solvent removal in vacuo (<lmm) at 95 °C gave the product as a yellow paste. H NMR (CDC1 3 ) indicated the presence of compounds I and J in an approximately 80:20 mole ratio. The lower temperamre reaction of these reactants gives little or no compound J. The synthesis of a mixmre of Compounds E and F, G and H, and I and J show that, especially at higher temperatures, the multifunctional carbonyl compound can be formed by nucleophilic acyl addition of a lactam anion at the carbonyl of a carbonate to produce an intermediate followed by reaction of a second lactam anion at the lactam carbonyl of the intermediate. The resulting multifunctional carbonyl compounds can then be reacted with a 4-aminopiperidine radical to provide a HALS mixmre which is an effective stabilizer. Generally the product produced in the lower temperamre reactions are less colored. Example 1.

The degree of conversion by NMR analysis was >97% . The mixmre was cooled to room temperamre and diluted with ethyl acetate. The organic solution was washed with water to remove excess amino alcohol and dried over magnesium sulfate. Filtration and removal of solvent under reduced pressure followed by further solvent removal in vacuo ( < 1 mm) at 95 °C gave 10.23 g (89%) of Compound II as a nearly colorless viscous oil.

A 250 mL single-necked reaction flask was equipped with a magnetic stirrer and a distillation head fitted with a thermometer, condenser, and receiving flask with a nitrogen inlet and outlet to a bubbler. To this flask was charged 4.3 g (11.57 mmol) of Compound B, 7.27 g (46.3 mmol) of 2,2,6, 6-tetramethy 1-4-piperidinol, and 200 mL of xylene.
