Description: Mono- and polvamides of perfluoroalkyl-substituted unsaturated acids FIELD OF THE INVENTION This invention relates to perfluoroalkyl-substituted mono-, di- and poly-amides derived from a perfluoroalkyl iodide, an unsaturated acid and a mono-, di-or polyamine. More particularly it relates to novel compounds which are the reaction products of a mono-, di- or polyamine of 60 to 2000 molecular weight with a perfluoroalkyl-substituted unsaturated acid or its corresponding lower alkyl ester and optionally a non-fluoπ ' nated amino-reactive compound such as an acid, ester, anhydride, epichlorohydrin, isocyanate or urea. These R F -amides are useful as internally or externally applied paper sizes to impart oil and grease resistance to paper, and as oil proofing coatings on textiles, wood, masonry and the like, or as high-performance surface active agents. BACKGROUND OF THE INVENTION The use of perfluoroalkyl-substituted polymers to impart oil and water repellency to a variety of substrates, textiles especially, has long been known. The vast majority of these polymers are perfluoroalkyl-substituted methacrylate copolymers. Several patents also describe RF-substituted polyurethanes, where Ft stands for a perfluoroalkyl moiety. Polyamide-amino polymers derived from polyethyleneimine by reaction with esters of perfluoroalkyl-substituted carboxylic acids are described in U.S. Patents 3,769,307 and 3,567,500. These polymers contain a mixture of Rp-substituted amide and secondary amino groups. These polymers are used to impart oleophobicity yet hydrophlilicity to textile substrates. Di-R F amido monocar- boxylic acids prepared from 1 equivalent of diethylenetriamine, 2 equivalents of an R F -acid and 1 equivalent of an anhydride are taught for use as textile finishes in U.S. Patent 3,754,026. Similar R F -amide-substituted polyethyleneimines useful as chemically resistant surfactants are described in U.S. Patent 3,271 ,430. They are obtained by reaction of a perfluorinated alkanoic acid with a large excess of ethyleneimine. Reaction products of R F -substituted acids with polymers bearing pendent primary amino groups attached to a carbon-carbon backbone by a linking group are claimed in U.S. Patent 4,606,973 as low surface energy coatings on flat substrates. U.S. Patent 5,643,864 describes the synthesis of anionic surfactants by reaction of, for example, triethylenetetramine with first, two equivalents of a long-chain carboxylic acid, and secondly with chloroacetic acid. R F -substituted acids are claimed as reactants but not described. U.S. Patent 5,750,043 and U.S. patent Application No. 09/234,251 describe water-soluble Rp-substituted carboxylic acids that are amides of polyamines of 100 to 100,000 molecular weight which are used as foam stabilizers for aqueous fire fighting foams It has now been discovered that unsaturated alkenoic acids, preferably ω-perfluoroalkyl substituted 10-undecenoic acid and tetrahydrophthalic acid, can be converted by reaction with a large variety of amines into mono-, di- and polyamides, which can be further reacted with non- fluorinated amino-reactive compounds such as acids, acid chlorides, esters, anhydrides, epichlorohydrin, isocyanates or urea to form monomeπ ' c and polymeric amides, amino-ethers, and ureas which are uniquely suitable - depending on their specific structure - as specialty surfactants or as oil and water repellents when applied to paper, textiles, wood, glass or masonry. Perfluoroalkyl substituents which are attached to a long-chain hydrocarbon moiety, such as an undecenoic group, exhibit improved surface activity and improved effectiveness as oil repellents, possibly because such long-chain hydrocarbyl groups, by their inter-chain interactions, aid in the orientation of the very poorly interacting R F -groups. ω-Perfluoroalkyl-substituted 10-undecenoic acid and its use as an oil repellent paper size is disclosed in U.S. Patent 5,491 ,261. Due to its relatively low molecular weight, this compound however shows substantial weight loss at the temperatures required for many paper product applications. This shortcoming has been overcome with the amide compounds of the present invention, which incorporate hydrogen-bonding amide groups and preferably contain more than one perfluoroalkyl-substituted undecenoic group.

The novel R F -products of the formula (I) or (II) can be synthesized in various ways. In one method, an aliphatic, cycloaliphatic or aromatic mono-, di- or polyamine is in a first step reacted with an R F -acid, -ester or -anhydride at temperatures of 50 to 260° C, depending on the reactivity of the acid or ester, to form the corresponding R F -amide intermediate which may contain unreacted secondary amino groups. This amidification reaction is preferably carried out in bulk, but aprotic diluents can be present. Preferably a catalyst such as phosphoric acid is employed. In a second step any remaining - mostly secondary - amino groups are reacted with an amino- reactive non-fluorinated compound. Useful reactants to convert remaining unreacted amino groups include anhydrides such as acetic anhydride, succinic and maleic anhydride, methendic and phthalic or tetrahydrophthalic anhydride; CrCβcarboxylic acids and their methyl esters; chloroacetic acid; alkyl halides such as allyl chloride; allyl glycidyl ether, urea and isocyanates. If the reactants are difunctional reactants they can act as chain-extending agents. Typical of such compounds are diacids and their lower alkyl esters, such as glutaric acid and dimethylsuccinate or dimethyladipate, or anhydrides such as succinic and maleic anhydride, methendic and phthalic anhydride, also dianhydrides such as benzene- and benzophenone tetracarboxylic acid dianhydride; epichlorohydrin; urea, and aliphatic, cycloaliphatic and aromatic diisocyanates with 6 to 2 carbon atoms, such as 1 ,6-hexane diisocyanate, 2,2,3(2,3,3)- trimethylhexane-1,6-diisocyante, cyclohexane diisocyanate, isophorone diisocyanate and toluene diisocyanate. If the starting polyamine (P) is for example N,N'-bis(3-aminopropyl) ethylenediamine, or a polyethyleneimine, the resulting reaction products are polyureas and polyamides. In an alternate process, which is especially useful to prepare the most preferred compositions of this invention, a linear terminally-unsaturated monocarboxylic acid or its lower alkyl ester, or tetrahydrophthalic anhydride is first reacted with a polyamine, to form an oligoamide with residual secondary amino groups. Preferably this reaction is carried out without a solvent. Although it is possible to use other linear terminally-unsaturated monocarboxylic acids, 10-undecenoic acid or its lower alkyl ester is preferred because R F substituents which are attached to the amino group through an intervening undecenoic group aid in the orientation of the R F groups and thereby improve their effectiveness as oil repellents. In a second step, the remaining secondary amino groups are reacted with an amino-reactive non-fluorinated compound of the type described above to form a fully substituted intermediate. Finally, this ethylenically unsaturated intermediate is reacted with an R F -iodide using a free radical generating mechanism as described for instance in U.S. Patent Nos. 5,585,517 and 5,693,747; and in copending U.S. Patent Application No. 09/691 ,486. Substituents -CH 2 CH=CH-R F or -CH 2 CH(OH)CH 2 -O-CH 2 -CH=CH -R F , where R F is defined as above can be incorporated into the compound by reaction of amino groups with allyl chloride or allyl glycidyl ether at any convenient stage during the synthesis, but before the addition of the R F -iodide. Halogen-containing compounds, such as allyl chloride, mono-chloroacetic acid, chloromethyl benzene, xylylene dichloride, or methyl iodide or bromide can be further used for quatemization of tertiary amino groups. Tertiary amino groups are always present in polyethyleneimines, and also if allyl chloride or allyl glycidyl ether are used as co-reactants. The final product mixture is then diluted, if desired, with sufficient deionized water to adjust the solids content to 15 to 50% and the fluorine content to 4 to 10%. Thus another aspect of the present invention is an essentially aqueous solution comprising 15 to 50% of a compound of the formula (I) or (II) as defined above. The compounds of the formula (I) or (II) as defined above are useful as internally or externally applied paper sizes to impart oil and grease resistance to paper, and oil and grease resistant coatings on textiles, wood, masonry and the like, or as high-performance surface active agents. When the compounds of the present invention are used as grease and oil repellent paper sizing agents, they are applied by methods known per se in amounts that are sufficient to deposit from 0.005 to 0.5% of organically bound fluorine by weight based on the dry paper weight. The compounds of the present invention can be applied externally in topical applications, for instance in a size press to the surface of paper or cardboard. They can also be applied internally, by adding them to an aqueous pulp together with other wet-end chemicals, as described for instance in U.S. Patent 5,091 ,550, the disclosure of which is incorporated by reference, and more generally in W.F. Reynolds, 'The Sizing of Paper", TAPPI Press, 1989. The compounds of the present invention are especially useful to impart oil and grease resistance to paper that is used for food packaging or contact applications. Thus another aspect of the present invention is a method to impart oil and grease resistance to paper, which comprises incorporating an amount of a compound of the formula (I) or (II) as defined above that is effective to impart oil and grease resistance into the paper. Advantageously this method comprises treating paper or pulp with essentially aqueous solution comprising a sufficient amount of a compound of the formula (I) or (II) as defined above to deposit from 0.005 to 0.5% of organically bound fluorine by weight based on the dry weight of the paper onto the paper or pulp. In addition to the fluorochemical, any of the conventional binders used in the paper industry - such as polymeric latex binders, carboxymethyl cellulose and polyvinyl alcohol - and sizing agents, such as ionic and nonionic starches such as ethoxylated and oxidized starches, and water sizing agents such as alkyl ketene dimer (AKD) or alkylsuccinic anhydride (ASA) can be employed. The present invention further relates to a method to impart oil and grease resistance to a textile material, which comprises treating the textile material with an amount of a compound of the formula (I) or (II) as defined above that is effective to impart oil and grease resistance to the textile material. The preferred amounts of the compounds of the present invention to treat the textile material are the same as for paper or pulp. The present invention further relates to textile material or paper or pulp which contains from 0.005 to 0.5% by weight of a compound of the present invention incorporated therein. The following examples describe certain embodiments of this invention, but the invention is not limited thereto. It should be understood that numerous changes to the disclosed embodiments could be made in accordance with the disclosure herein without departing from the spirit or scope of the invention. These examples are therefore not meant to limit the scope of the invention. Rather, the scope of the invention is to be determined only by the appended claims and their equivalents. In these examples all parts given are by weight unless otherwise indicated. Unless otherwise noted, in the following non-limiting examples the perfluoroalkyl iodide (R F I) used is Zonyl Tel A-N from DuPont, with a homologue distribution of 53.0% C 8 F 17 I, 30.6% Ci 0 F 21 l, 11.7% Cι 2 F 25 l, 3.6% Cι 4 F 29 l, and 1.0% C 16 F 33 I.

After 1.5 hours, a creamy, off-white dispersion is obtained which can be used for performance evaluation. Examples 23 - 24 show the performance of the novel Rp-compounds as internal and external paper sizes. Example 23 Performance of the new compounds as External Paper Sizes- Example Preparation and Testing: The required amounts of 2% solutions of the test compounds in distilled water are dissolved in enough aqueous ammonia to achieve complete neutralization of the acid groups; the pH of the resulting solutions or dispersions is 9 to 9.5. Samples of the fluorochemicals are then diluted to the test application levels with distilled water. The neutralized test solutions are added to a 4% aqueous solution of paper maker's starch (Stayco M, oxidized starch, from Staley Corp.) and then applied to unsized paper by padding (paper dipped through starch solution, and passed through single nip rollers). The resulting sheets are dried at ambient conditions for 15 minutes, then 3 minutes at 200° F (93° C) in an "Emerson Speed Drier" (heated metal plate with canvas cover). Oil Kit Test: The oil repellency of the surface is determined by using the TAPPI UM 557 OIL KIT TEST, which consists of determining with which of twelve castor oil-heptane-toluene mixtures having decreasing surface tension penetration occurs within 15 seconds; ratings go from 1 , lowest, to 12. Ralston-Purina (RP2) Test: Grease resistance is determined with the Ralston-Purina test for pet food materials; RP-2 Test, Ralston-Purina Company, Packaging Reference Manual Volume 06 - Test Methods. - In summary: cross-wise creased test papers are placed over a grid sheet imprinted with 100 squares. Five grams of sand are placed in the center of the crease. A mixture of synthetic oil and a dye for visualization is pipetted onto the sand and the samples are maintained at 60° C for 24 hours. Ratings are determined by the percentage of stained grid segments, using at least two samples. Turpentine Test, according to TAPPI T454om-94, is a preliminary test to determine rates at which oil or grease can be expected to penetrate paper. Cobb Size Test Water resistance is determined using the Cobb Sizing test as described in TAPPI T 441om-90. Table 1 : Performance of new compounds as external paper sizes Example 24 Performance of new compounds as internal paper sizes Example Preparation and Testing: Six grams of dry recycled pulp consisting of 70% hardwood and 30% softwood are diluted in 289 ml distilled water and thoroughly dispersed in a blender. To this pulp slurry is added the required amount of a 1 % solution of the test compound in distilled water and mixed in for 5 minutes. Then 6 ml of a 1% aqueous solution of cooked cationic starch are added and mixed together for an additional 5 minutes. To this mixture 24 ml of a 50% (on solids) dilution of a water-repellent adjuvant AKD (alkyl-ketene-dimer; Hercon-76, from Nalco Chem. Corp.) are added and mixed in for another 10 minutes. The resulting slurry is diluted with an additional 500 ml of distilled water and mixed again. This mixture is then poured over a 100-mesh wire screen, with a vacuum applied from below that pulls the water from the pulp mixture to form a sheet on the screen. The wet sheet is removed from the screen and dried between another screen and a hard surface at a pressure of approximately 0.4 Ib./in at 110° C for 1 1/2 hours. Hot- Oil Test for molded paper (internal size): One ml of hot (110° C) com oil is placed on paper and the time is recorded for penetration to occur (20 minutes maximum). Paper made in the same manner, including the cationic starch and water-repellent adjuvant, but without a fluorochemical, demonstrates an oil kit number of < 1 and holds the hot corn oil for less than one minute (begins to penetrate as soon as applied). The amount of oil absorbed is determined gravimetrically by weighing the paper before and after the hot-oil test, and after the surface oil has been removed. Hot-Water Test for molded paper (internal size): One ml of a hot (83° C) 5% lactic acid solution is placed on the paper plate, and hold-out time and absorption are measured the same way as in the hot-oil test. The results are shown in the following table. Table 2: Performance of new compounds as internal paper sizes
