FLUORINATED SOLID ACIDS AS CATALYSTS FOR THE PREPARATION OF HYDROCARBON RESINS

Abstract: Fluorinated solid acids and supported fluorinated solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomoer, C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the fluorinated solid acid catalyst and/or supported fluorinated solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5 DEG C to 170 DEG C can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerization catalysts since the acid sites are an integral part of the solid. The fluorinated solid acid catalysts and supported fluorinated solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or by-products.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to fluorinated solid acids and supported fluorinated solid acids useful as catalysts for the polymerization of a feed stream containing at least one of pure monomer, C5 monomers, and C9 monomers to produce a hydrocarbon resin, to processes of preparing hydrocarbon resins using fluorinated solid acid catalysts and supported fluorinated solid acid catalysts, and to hydrocarbon resins produced by such processes. 2. Discussion of Background Hydrocarbon resins are low molecular weight, thermoplastic materials prepared via thermal or catalytic polymerization. The resins may be derived from several different sources of monomers. The monomer sources include cracked petroleum distillate from oil refining, turpentine fractions (e.g., terpenes from natural product distillation), paper mill byproduct streams, coal tar, and a variety of pure olefinic monomers. The resulting hydrocarbon resins can range from viscous liquids to hard, brittle solids with colors ranging from water white to pale yellow, amber, or dark brown depending on the monomers used and the specific reaction conditions. Typically, pure monomer resins tend to be water white, C9 monomer resins tend to be amber to brown, and C5 monomer resins tend to be yellow. Hydrocarbon resins are used extensively as modifiers in adhesives, rubber, hot-melt coatings, printing inks, paint, flooring, and other applications. The resins are usually used to modify other materials. Pure monomer hydrocarbon resins can be prepared by cationic polymerization of styrene-based monomers such as styrene, alpha-methyl styrene, vinyl toluene, and other alkyl substituted styrenes using Friedel-Crafts polymerization catalysts such as Lewis acids (e.g., boron trifluoride (BF 3 ), complexes of boron trifluoride, aluminum trichloride (A1C1 3 ), alkyl aluminum chlorides). Similarly, aliphatic C5 hydrocarbon resins can be prepared by cationic polymerization of a cracked petroleum feed containing C5 and C6 paraffins, olefms, and diolefms also referred to as "C5 monomers". These monomer streams are comprised of cationically polymerizable monomers such as 1,3-pentadiene which is the primary reactive component along with cyclopentene, pentene, 2-methyl-2-butene, 2-methyl-2-pentene, cyclopentadiene, and dicyclopentadiene. The polymerizations are catalyzed using Friedel- Crafts polymerization catalysts such as Lewis acids (e.g., boron trifluoride (BF 3 ), complexes of boron trifluoride, aluminum trichloride (A1C1 3 ), or alkyl aluminum chlorides). In addition to the reactive components, nonpolymerizable components in the feed include saturated hydrocarbons which can be codistilled with the unsaturated components such as pentane, cyclopentane, or 2-methylpentane. This monomer feed can be copolymerized with C4 or C5 olefins or dimers as chain transfer agents. Also, aromatic C9 hydrocarbon resins can be prepared by cationic polymerization of aromatic C8, C9, and/or CIO unsaturated monomers derived from petroleum distillates resulting from naphtha cracking and are referred to as "C9 monomers". These monomer streams are comprised of cationically polymerizable monomers such as styrene, alpha- methyl styrene, beta-methyl styrene, vinyl toluene, indene, dicyclopentadiene, divinylbenzene, and other alkyl substituted derivatives of these components. The polymerizations are catalyzed using Friedel-Crafts polymerization catalysts such as Lewis acids (e.g., boron trifluoride (BF 3 ), complexes of boron trifluoride, aluminum trichloride (A1C1 3 ), alkyl aluminum chlorides). In addition to the reactive components, nonpolymerizable components include aromatic hydrocarbons such as xylene, ethyl benzene, cumene, ethyl toluene, indane, methyhndane, naphthalene and other similar species. These nonpolymerizable components of the feed stream can be incorporated into the resins via alkylation reactions. Although Lewis acids are effective catalysts for the cationic polymerization reactions to produce hydrocarbon resins, they have several disadvantages. Conventional Lewis acids are single use catalysts which require processing steps to quench the reactions and neutralize the acids. Further, conventional Lewis acids also require removal of catalyst salt residues from the resulting resin products. Once the salt residues generated from the catalyst neutralization are removed, the disposal of these residues presents an additional cost. Therefore, it is of particular interest to reduce the amount of catalyst residues, particularly halogen-containing species generated in these reactions. Another problem involved in using conventional Lewis acid catalysts, such as A1C1 3 and BF 3 , is that they are hazardous materials. These conventional Lewis acid catalysts generate highly corrosive acid gases on exposure to moisture, (e.g., HF, HC1). In addition to the traditional Lewis acids, work has been done with certain solid acid catalysts. BITTLES et al., "Clay-Catalyzed Reactions of Olefms. I.

In this regard, no attempt is made to show details of the invention in more detail than is necessary for a fundamental understanding of the invention, the description making apparent to those skilled in the art how the several forms of the invention may be embodied in practice. All percent measurements in this application, unless otherwise stated, are measured by weight based upon 100% of a given sample weight. Thus, for example, 30% represents 30 weight parts out of every 100 weight parts of the sample. Unless otherwise stated, a reference to a compound or component includes the compound or component by itself, as well as in combination with other compounds and components, such as mixtures of compounds. Before further discussion, a definition of the following terms will aid in the understanding of the present invention. SOLID ACID: a solid which changes the color of a basic Hammett indicator with a pK a < 0. FLUORINATED SOLID ACID CATALYST: a solid acid catalyst comprising a fluorinated alkane group attached to a sulfonate functional group (e.g., Brønsted acids such as perfluorooctanesulfonic acid or sulfonic acid resins, or Lewis acids including a fluorinated alkane group attached to a sulfonate group which is covalently bonded to a metal, e.g., aluminum triflate or ytterbium triflate). SUPPORTED FLUORINATED SOLID ACID CATALYST: a solid acid catalyst comprising a support, e.g., silica, silica-alumina, clay, zeolite, associated with a fluorinated acid having a fluorinated alkane group that is attached to a sulfonate functional group (e.g., Brønsted acids such as perfluorooctanesulfonic acid or sulfonic acid resins, or Lewis acids including a fluorinated alkane group attached to a sulfonate group that is attached to a metal, e.g., aluminum triflate or ytterbium triflate). HYDROCARBON RESIN: a low molecular weight (i.e., a number average molecular weight of about 200 to less than about 3000 as determined by size exclusion chromatography (SEC)) thermoplastic polymer synthesized via thermal or catalytic polymerization of cracked petroleum distillates, terpenes, coal tar fractions, or pure olefinic monomers, wherein one of the monomers is at least a C5 or higher. PURE MONOMER: a composition comprising synthetically generated or highly purified monomer species, e.g., styrene from ethyl benzene or alpha-methyl styrene from cumene. PURE MONOMER FEED STREAM: a composition comprising any number of pure monomer species.

FREELY-ASSOCIATED WATER: water associated with a solid acid catalyst or support where the water is chemisorbed and/or physisorbed. As a general overview of the present invention, hydrocarbon resins are produced by using fluorinated solid acids as catalysts for the cationic polymerization of a feed stream containing at least one of pure monomer (e.g., styrene based monomers), C5 monomers, and C9 monomers. Resins with softening points (Ring and Ball) preferably in the range of about 5°C to 170°C, more preferably about 30°C to 150°C, can be prepared. These catalysts offer advantages over the traditional Lewis acid polymerization catalysts since the acid sites are an integral part of the solid. Further, for the supported fluorinated solid acids, the fluorinated acid is supported on a solid and therefore can be removed from the reaction. Looking at the present invention in more detail, hydrocarbon resins are prepared through a polymerization reaction wherein a feed stream containing at least one of pure monomer, C5 monomers, and C9 monomers are contacted with a fluorinated solid acid catalyst.

In selecting other fluorinated solid acid catalysts which may be useful in the present invention, it is generally true that the fluorinated solid acid catalyst should be more acidic than about -3 on the Hammett scale. For the lanthanide perfluoroalkanesulfonic acid complexes and supported lanthanide perfluoroalkanesulfonic acid complexes, preferred lanthanides include Yb, La, Nd, and Y.

In addition to clays, other supports include silica, silica-alumina, mesoporous silica, mesoporous silica-alumina, and ion exchange resins. Other types of supports includes natural or synthetic zeolites such as zeolite Y, zeolite β (i.e., BEA), MFI (e.g., "Zeolite Sacony Mobil-5" ("ZSM-5")), MEL (e.g., "Zeolite Sacony Mobil-11" ("ZSM-11")), NaX, NaY, faujasite (i.e., FAU), and mordenite (i.e., MOR).

Before use, the fluorinated solid acid catalysts may be treated to remove freely- associated water to maximize the catalyst acidity and activity toward the polymerization. The freely-associated water may be removed by various techniques, including thermal treatment, reduced pressure treatment, dry atmosphere treatment such as nitrogen or air, or a combination thereof. While not wishing to be bound by theory, removing freely- associated water maximizes the acid strength of the fluorinated solid acid catalysts and makes the polymerizations more reproducible. The freely-associated water may be removed from the fluorinated solid acid catalyst and/or supports by calcining which generally means heating the fluorinated solid acid catalyst and/or support to high temperature without fusing the catalyst. The fluorinated solid acid catalyst and/or support may be calcined under an inert atmosphere, such as nitrogen or dry air, or under reduced pressure. The calcining is performed for preferably up to about 8 hours or more, more preferably about 1 hour to 4 hours, preferably at temperatures up to about 700°C, more preferably about 150°C to 250°C. The freely-associated water removed from the fluorinated solid acid catalyst and/or support may have been derived from water (physisorbed water) or hydroxyl groups (chemisorbed water) associated with the fluorinated solid acid catalyst and/or support. By removal of substantially all freely-associated water is meant removing all or essentially all physisorbed water and removing at least a majority of chemisorbed water. It has been discovered that by controlling the conditions under which the fluorinated solid acid catalyst and/or support is calcined, such as controlling the temperature or time under which the calcination step takes place, tailoring of the physical properties of the resultant resin, such as its softening point or its molecular weight, may be achieved. Many of the fluorinated solid acid catalysts of the present invention are most effective in the presence of a controlled amount of water in the feed stream. For instance, the feed stream should include less than about 500 ppm water, preferably less than about 200 ppm water, more preferably less than about 100 ppm water, and most preferably less than about 50 ppm water. Pure monomer feed streams may contain relatively pure styrene-based monomers such as styrene, alpha-methyl styrene, beta-methyl styrene, 4-methyl styrene, and vinyl toluene fractions. The monomers can be used as pure components or as blends of two or more monomer feeds to give desired resin properties. Preferred blends include about 20 wt% to 90 wt% alpha-methyl styrene with about 80 wt% to 10 wt% of one or more comonomers, preferably styrene, vinyl toluene, 4-methyl styrene or blends of these components. In addition, other alkylated styrenes can be used as monomers in this invention such as t-butyl styrene or phenyl styrene. Feed streams can be dried, if desired, and preferably contain less than about 200 ppm water, more preferably less than about 100 ppm water, and most preferably less than about 50 ppm water. In the case of C5 resins, the petroleum feed streams contain unsaturated C5 and/or C6 olefms and diolefms boiling in the range from about 20 °C to 100°C, preferably about 30°C to 70°C. In some cases, cyclopentadiene and methylcyclopentadiene components are removed from the feed by heat soaking at temperatures between preferably about 100 °C and 160°C, and fractionating by distillation. Monomers found in these feedstocks may include but are not limited to olefins such as isobutylene, 2-methyl-2-butene, 1 -pentene, 2-methyl-l- pentene, 2-methyl-2-pentene, as well as 2-pentene, cycloolefins such as cyclopentene, and cyclohexene, diolefms such as 1,3-pentadiene, 1,4-pentadiene, isoprene, 1,3-hexadiene, and 1 ,4-hexadiene, cyclodiolefins such as cyclopentadiene, dicyclopentadiene, and alkyl substituted derivatives and codimers of these cyclodiolefins. Commercial samples of this type of feed include, but are not limited to "Naphtha Petroleum 3 Piperylenes" from Lyondell Petrochemical Company, Houston, TX, regular "Piperylene Concentrate" or "Super Piperylene Concentrate" both from Shell Nederland Chemie B.V., Hoogvilet, the Netherlands. The C5 feed streams generally contain at least about 70 wt% polymerizable monomers with at least about 50 wt% 1,3-pentadiene. The C5 feed stream may contain low levels of isoprene, generally contains a portion of 2-methyl-2-butene, and may contain one or more cyclodiolefin. Also concerning C5 monomer feed streams, in addition to the reactive components, nonpolymerizable components in the feed may include saturated hydrocarbons which can be codistilled with the unsaturated components such as pentane, cyclopentane, or 2- methylpentane. This monomer feed can be copolymerized with C4 or C5 olefins or dimers as chain transfer agents. Chain transfer agents may be added to obtain resins with lower and narrower molecular weight distributions than can be prepared from using monomers alone. Chain transfer agents stop the propagation of a growing polymer chain by terminating the chain in a way which regenerates a polymer initiation site. Components which behave as chain transfer agents in these reactions include but are not limited to isobutylene, 2-methyl- 1-butene, 2-methyl-2-butene or dimers or oligomers of these species. The chain transfer agent can be added to the reaction in pure form or diluted in a solvent. Feed streams can be dried if desired and preferably contain less than about 500 ppm water, more preferably less than about 200 ppm water, and most preferably less than about 50 ppm water. In the case of C9 monomer resins, the feed streams contain unsaturated aromatic C8, C9, and/or CIO monomers with a boiling range of about 100°C to 300°C at atmospheric pressure. Aromatic C8-C10 feed streams (also referred to as C9 feed streams) can be derived from steam cracking of petroleum distillates. Monomers found in these feed stocks may include but are not limited to styrene, vinyl toluene, indene, dicyclopentadiene, and alkylated derivatives of these components. Commercial samples of this type of feed include but are not limited to "LRO-90" from Lyondell Petrochemical Company, Houston, TX, "DSM C9 Resinfeed Classic" from DSM, Geleen, the Netherlands, "RO-60" and "RO-80" from Dow Chemical Company of Midland, Michigan, and "Dow Resin Oil 60-L" from the Dow Chemical Company of Terneuzen, the Netherlands. The C9 feed stream generally contains at least about 20% by weight, preferably about 30% to 75% by weight, and most preferably about 35% to 70% by weight polymerizable unsaturated hydrocarbons. The remainder is generally alkyl substituted aromatics which can be incorporated into the resins by alkylation reactions. Feed streams can be dried if desired and preferably contain less than about 500 ppm water, more preferably less than about 200 ppm water, and most preferably less than about 50 ppm water. The feed streams may be limited to pure monomer, C5 monomers, or C9 monomers. Alternatively, cofeed streams can be used in combination with main feed streams of pure monomer, C5 monomers, or C9 monomers. Depending upon the main feed stream, pure monomer, C5 monomers, C9 monomers, or even terpenes, and any combination thereof, may serve as a cofeed stream. Terpene feed stocks include but are not limited to d- limonene, alpha- and beta-pinene, as well as dipentene. Resins from blends of main feed streams with cofeed streams may be prepared in the range of about 30 wt% to 95 wt% main feed with about 70 wt% to 5 wt% of a cofeed, preferably about 50-85 wt% main feed and about 50 wt% to 15 wt% cofeed. The polymerization feed stream preferably contains between about 20 wt% and 80 wt% monomers, more preferably about 30 wt% to 70 wt%, and most preferably about 40 wt% to 70 wt%. In the case of C5 resins, the feed may contain up to about 40 wt% of a chain transfer agent, more preferably up to about 20 wt%, chain transfer agents as discussed above. The feed stream also contains about 80 wt% to 20 wt% of a solvent such as toluene, octane, higher boiling aromatic solvent, aliphatic solvent, or solvent blend. Regarding the solvents, for pure monomer polymerization, the preferred solvents are aromatic solvents. Typically toluene, xylenes, or light aromatic petroleum solvents such as "Aromatic 100" from Exxon Chemical Company, Houston, TX, "HiSol 10" from Ashland Chemical Incorporated, Columbus, OH, and "Cyclosol 53" from Shell Chemical Company, Houston, TX can be used. These solvents can be used fresh or recycled from the process. The solvents generally contain less than about 200 ppm water, preferably less than about 100 ppm water, and most preferably less than about 50 ppm water. For C5 polymerization, the preferred solvents are aromatic solvents. Generally, unreacted resin oil components are recycled through the process as solvent. In addition to the recycled solvents, toluene, xylenes, or aromatic petroleum solvents such as "Solvesso 100" from Exxon Chemical Company, Houston, TX and "Shellsol A" from Shell Chemical Company, Houston, TX can be used. These solvents can be used fresh or recycled from the process. The solvents generally contain less than about 500 ppm water, preferably less than about 200 ppm water, and most preferably less than about 50 ppm water. For C9 polymerization, the preferred solvents are aromatic solvents. Generally, unreacted resin oil components are recycled through the process as solvent. In addition to the recycled solvents, toluene, xylenes, or aromatic petroleum solvents such as "Solvesso 100" from Exxon Chemical Company, Houston, TX and "Shellsol A" from Shell Chemical Company, Houston, TX can be used. These solvents can be used fresh or recycled from the process. The solvents generally contain less than about 200 ppm water, preferably less than about 100 ppm water, and most preferably less than about 50 ppm water. Concerning the polymerization reaction conditions, a first important variable is the amount of fluorinated solid acid catalyst which is used. The fluorinated solid acids are preferably used at a level of about 0.1 wt% to 30 wt% based on the weight of the monomer. For pure monomer resins, the fluorinated solid acid concentration is preferably about 0.1 to 15 wt%, more preferably about 0.5 wt% to 10 wt%, and most preferably about 0.5 wt% to 8 wt%. For C5 monomers, the fluorinated solid acid concentration is preferably about 0.5 wt% to 30 wt%, more preferably about 1 wt% to 20 wt%, and most preferably about 3 wt% to 15 wt%. For C9 monomers, the fluorinated solid acid concentration is preferably about 0.5 wt% to 30 wt%, more preferably about 1 wt% to 20 wt%, and most preferably about 3 wt% to l5 wt%. A second important variable in the reaction is the reaction sequence, i.e., the order and manner in which reactants are combined. In one reaction sequence, the catalyst can be added to a solution of the monomers incrementally while controlling the reaction temperature. Alternatively, in another reaction sequence, the monomer can be added incrementally to a slurry of the fluorinated solid acid catalyst in a solvent. For a set catalyst level and reaction temperature, substantially lower softening point resins are obtained when the monomer is added to a catalyst slurry. As discussed in more detail in the following paragraphs, lower molecular weights and narrow polydispersity, i.e., Mw/Mn, as measured by size exclusion chromatography, are expected when the monomer is added to the catalyst solution compared with resins where the catalyst is added to the monomer. The molecular weight averages of the resins were measured using size exclusion chromatography, SEC. The column set for the analysis consisted of four Waters "Ultrastyragel" columns of 500, 500, 1000, and 100 A pore size, in series, (Part Nos. WAT 010571, 010571, 010572, 010570 respectively) available from Waters Corporation, Milford, MA. The molecular weight calibration was calculated from the peak elution times of a standard set of narrow molecular weight distribution polystyrene polymers. The calibration set encompassed 18 standards ranging in peak molecular weight from 162 to 43,900. The peak molecular weight of a narrow molecular weight standard is defined as equal to (MwMn)' Λ (ASTM test method D3536-76). The calibration curve is defined by a third degree polynomial curve fit of a plot of log MW vs. V e /V r , where V e is the elution volume of the standard and V r is the elution volume of the reference peak, oxygen, present as dissolved air in the injected solution. The columns and detector cell (Hewlett-Packard Differential Refractometer) are maintained at 40 °C. The solvent (mobile phase) is tetrahydrofuran containing 250 ppm butylated hydroxytoluene (BHT, 2,6-di-tert-butyl-4- methylphenol) as a stabilizer (the tetrahydrofuran with BHT being available from Burdick and Jackson, Muskegon, MI). The mobile phase reservoir is purged with helium and is maintained at a flow rate of 1 milliliter per minute. Under these conditions, BHT eluted at 35.86 minutes. Samples are dissolved in THF, 0.25% wt/vol, and filtered through a 0.45 micron pore size "TEFLON" (polytetrafluoroethylene) membrane filter prior to injection (200 microliters) into the chromatograph. The reported molecular weights are the "polystyrene equivalent" molecular weights as calculated from the calibration curve. For the pure monomer resins, the resins produced using the current invention have number average molecular weights (Mn) ranging from about 400 to 2000, weight average molecular weights (Mw) ranging from about 500 to 5000, Z average molecular weights (Mz) ranging from about 500 to 10,000, and polydispersities (PD) as measured by Mw/Mn between about 1.2 and 3.5, typically between about 1.2 and 2.5. For the C5 hydrocarbon resins, the resins produced using the current invention have number average molecular weights (Mn) ranging from about 400 to 2000, weight average molecular weights (Mw) ranging from about 500 to 3500, Z average molecular weights (Mz) ranging from about 700 to 15,000, and polydispersities (PD) as measured by Mw/Mn between about 1.2 and 5, typically between about 1.2 and 3.5. For the C9 hydrocarbon resins, the resins produced using the current invention have number average molecular weights (Mn) ranging from about 400 to 1200, weight average molecular weights (Mw) ranging from about 500 to 2000, Z average molecular weights (Mz) ranging from about 700 to 6000, and polydispersities (PD) as measured by Mw/Mn between about 1.2 and 3.5, typically between about 1.2 and 2.5. As mentioned previously, it is expected that narrower polydispersities and lower molecular weights are obtained when the monomer is added to the catalyst solution than when the catalyst is added to the monomer. Taking into consideration the effect of the reaction sequence, it is expected that polydispersities more narrow than those obtained using traditional Lewis acid Friedel-Crafts catalysts can be obtained using the fluorinated solid acids if desired. Narrow polydispersity is important to ensure compatibility of resin with polymers in end use applications. A third important reaction variable is the reaction temperature. Polymerization temperatures between about -50°C and 150°C can be used in these reactions, however, more preferred reaction temperatures are between about -20°C and 100°C, most preferred temperatures are between about 0°C and 70°C. For pure monomer, the reaction temperature is preferably between about -50°C and 100°C, more preferably between about -20°C and 75 °C, and most preferably between about -10°C and 60°C. For C5 monomers, the reaction temperature is preferably between about -50°C and 100°C, more preferably between about -20 °C and 75 °C, and most preferably between about -10°C and 70 °C. For C9 monomers, the reaction temperature is preferably between about 0°C and 150°C, more preferably between about 10°C and 120°C, and most preferably between about 20°C and 110°C. Temperature is found to have a significant effect on the properties of the resulting resins. Higher molecular weight and high softening point resins are prepared at lower reaction temperatures. The reaction time at reaction temperature is preferably between about 30 minutes and 8 hours, and more preferably between about 1 hour and 4 hours. The polymerization process can be carried out as a continuous, semi-batch, or batch process in such diverse reactors as continuous, batch, semi-batch, fixed bed, fluidized bed, and plug flow. For instance, in continuous processes, a solution of the monomers can be passed over the catalyst in a fixed bed, or the monomers can be cofed with a catalyst slurry into a continuous reactor. The reaction may be stopped by physically separating the solid catalysts from the products. Physical separation may render the reaction solution neutral. Furthermore, physical separation can be performed by simple filtration or by separation of the resin solutions from a fixed catalyst bed. As a result, physical separation is easy and complete such that, for many fluorinated solid acid catalysts, acid functionality and catalyst residue are not left in the resin product. If leaching of acid is possible, then acid neutralization is required. This step is commonly known in the art as "quenching". For the fluorinated solid acid catalysts which require quenching, less salt is generated than by traditional Lewis acid catalysts. Thus, use of fluorinated solid acid catalysts minimizes or eliminates the need for extra processing steps to quench the reactions, neutralize the catalyst, and filter the catalyst salt residues from the resulting products. Once the fluorinated solid acid catalyst and resin solution are separated, the resin solution can be stripped to remove unreacted hydrocarbons, solvents, and low molecular weight oligomers which can be recycled through the process. Resins obtained from this invention typically have softening points as measured by ASTM-E28 "Standard Test Method for Softening Point by Ring and Ball Apparatus" (revised 1996), varying from preferably about 5 °C to 170°C, more preferably from about 30°C to 150°C. For pure monomer, the softening points preferably range from about 5°C to 170°C, more preferably from about 50°C to 150°C. For C5 hydrocarbon resins, the softening point preferably ranges from about 5°C to 170°C, more preferably from about 50°C to 150°C, and most preferably about 70°C to 130°C. For C9 hydrocarbon resins, the softening point is preferably up to about 170°C, and the softening point range is most preferably from about 70 °C to 160°C. Flowable resin or those that are liquids at room temperature can also be prepared if desired using proper reaction conditions. After the resin is produced, it may be subsequently subjected to hydrogenation to reduce coloration and improve color stability. Hydrogenation of resins is well known in the art. For a discussion of hydrogenation, reference is made to U.S. Patent No. 5,491,214 to DAUGHENBAUGH et al., which is incorporated herein by reference in its entirety. The resins of the current invention can be used as modifiers in adhesives, sealants, printing inks, protective coatings, plastics, road markings, flooring, and as dry cleaning retexturizing agents. The fluorinated solid acid catalysts of the present invention offer several advantages over Lewis acids (e.g., A1C1 3 , AlBr 3 , BF 3 , complexes of BF 3 , TiCl 4 , and others which are traditionally used for Friedel-Crafts polymerizations). Many of these advantages are a result of the acid sites being an integral part of the solid catalysts, and/or are a result of the fluorinated acid being combined with a support. Because the acid sites are an integral part of the solid catalyst and/or the fluorinated acid is combined with a support, contamination of the resin products or solvents with catalyst residues is minimal. The fluorinated solid acid catalysts of the present invention can generally be regenerated and recycled to thereby minimize waste disposal of spent catalyst. In contrast, the Lewis acids are generally single use catalysts. Further, the fluorinated solid acid catalysts of the present invention are nonhazardous when compared with traditional Lewis acid catalysts such as BF 3 and A1C1 3 . The catalysts of the present invention generally do not generate corrosive or hazardous liquid or gaseous acids on exposure to moisture. Concerning aluminum tris(trifluoromethanesulfonate), aluminum triflate, Al(OSO 2 CF 3 ) 3 , this catalyst is useful for the preparation of hydrocarbon resins from C5 monomer feeds containing 1,3-pentadiene as well as other linear, branched and cyclic olefin containing species. Aluminum triflate is a white solid which is insoluble in organic solvents. It has been found that aluminum triflate behaves as a very strong solid acid catalyst for the cationic polymerization of C5 monomer feeds comprised of 1 ,3-pentadiene and other olefins to prepare C5 hydrocarbon resins. The catalytic activity of the aluminum complex appears to be a function of the moisture level both in the complex and in the reaction solution. A low level of residual water in the reaction solution allows the aluminum complex to have extremely strong acid character resulting in significant reaction of the double bonds in the monomer feedstock. Higher water levels appear to attenuate the acid strength of the aluminum triflate leading to a lower degree of olefin reaction in the resulting polymers. The aluminum triflate is an effective catalyst in the presence of cocatalysts, such as acetic acid, which can serve to modulate the activity of the complex and alter the reaction products. The combined effect of aluminum triflate loading, cocatalysts such as water or protic acids, and reaction conditions such as reaction temperature and monomer dilution can serve as effective means to control the cationic polymerization of C5 monomer feeds and prepare C5 hydrocarbon resins with a range of properties. The use of water as a modulator is described in PENG et al., cited above, the disclosure of which has been incorporated by reference. The present invention will be further illustrated by way of the following Examples. Examples 1 and 2 involve pure monomer resins, Examples 3-37 involve C5 resins, and Examples 38-46 involve C9 resins. These examples are non-limiting and do not restrict the scope of the invention. Unless stated otherwise, all percentages, parts, etc. presented in the examples are by weight. EXAMPLE 1 This example illustrates the use of catalyst prepared from trifluoromethanesulfonic acid (triflic acid) and clay for the polymerization of pure monomer. CATALYST PREPARATION In a 1 liter 3 neck flask, 150 grams of toluene and 100 grams "F-22" Bentonite acid- leached powder (available from Engelhard, Corporation, Jackson Mississippi) were agitated with an overhead stirrer. A solution of 10 grams of trifluoromethanesulfonic acid in 100 grams of toluene was added over 45 minutes. The resulting solution was stirred for 21 hours. After filtration and washing with toluene, acetone, and water, the material was rotary evaporated for 6 hours at 130° C and 6 mm Hg. POLYMERIZATION A 500 milliliter three neck flask was equipped with a cooling jacket overhead stirrer, reflux condenser, gas inlet and outlet ports, thermometer, and solid addition funnel. The flask was charged with 36.6 grams of styrene (reagent grade, Aldrich, Milwaukee, WI), 86.6 grams of alpha-methyl styrene (reagent grade, Aldrich, Milwaukee, WI), and 100 grams of toluene (reagent grade, Aldrich, Milwaukee, WI). Prior to use, the styrene and alpha-methyl styrene were dried over molecular sieve and alumina (reagent grade, Aldrich, Milwaukee, WI). Also prior to use, the toluene was dried over 3 angstrom molecular sieves. The trifluoromethanesulfonic acid on clay as prepared above, 4.0 grams, was calcined at 200 °C for 2 hours. After calcining, the 4.0 grams of catalyst was added to the reaction mixture. The temperature was maintained at 0°C ± 6°C for 180 minutes. At the end of the reaction time, the catalyst was filtered from the reaction solution. The resin solution was rotary evaporated with a final condition of 45 minutes with a 190°C bath temperature at < 5 mm Hg. The resulting resin had the properties listed in Table 1. TABLE 1 EXAMPLE 2 This example illustrates the use of a lanthanide triflate as a catalyst for the polymerization of a pure monomer feed. CATALYST PREPARATION Ytterbium triflate (Yb(O 3 SCF 3 ) 3 ≡ Yb(OTf) 3 ) was found to be able to polymerize alpha-methyl styrene (AMS) and styrene mixtures in =100% yield. The ytterbium triflate was prepared by adding an excess of ytterbium oxide (Yb 2 O 3 ) (99.9% purity) to an aqueous solution of trifluorosulfonic acid (50% v/v) and heating at 95°C for 90 minutes. The mixture was then filtered to remove the unreacted oxide, and water was removed from the filtrate under reduced pressure. The yield of ytterbium triflate was 104% or 13.87 g. The yield being above 100% due to retained moisture. Prior to using the material as a catalyst, the ytterbium triflate was dried by heating under a stream of inert gas at 180°C to 200°C for 2 hours. A 50:50 AMS/styrene mixture was polymerized in toluene at approximately 0°C to give a polymeric material possessing a number average molecular weight (Mn) of 429, weight average molecular weight (Mw) of 677, a Z average molecular weight (Mz) of 1396, and a polydispersity (PD) of 1.58. It should be noted that the addition of the olefinic monomer to the solid Yb(OTf) 3 catalyst resulted in a spontaneous polymerization exotherm. EXAMPLES 3-5 These examples illustrate the use of perfluorinated sulfonic acids as catalysts for the polymerization of piperylene concentrate, a C5 monomer feed. CATALYST PREPARATION Perfluorooctanesulfonic acid was prepared from the potassium salt according to the methods outlined in Synthetic Communications, 1991, 21, 1273-1279 as follows. The potassium salt of perfluorooctanesulfonic acid (98% PCR, Gainesville, FL), 22.4 grams, was added to a 100 milliliter round bottom flask fitted with a magnetic stirring bar, thermometer, and nitrogen inlet and outlet ports. Sulfuric acid (J. T. Baker, Pillipsburg, NJ), 22.4 grams, was added to the reaction flask. After purging the flask with nitrogen, the reaction mixture was heated to 130-135°C for three hours. The temperature was increased to 175-180°C for an additional three hours. On cooling, a solid product formed and the sulfuric acid was decanted from the product. The product was purified by vacuum distillation at 140-160°C at 0.25 mm Hg. The acid product yield was 87% based on the starting potassium salt. The perfluorooctanesulfonic acid was handled under a dry inert atmosphere and stored in a desiccator prior to use. POLYMERIZATION A 500 milliliter three neck flask was equipped with an overhead stirrer, reflux condenser, gas inlet and outlet ports, a thermometer and a dropping addition funnel. The flask was charged with 60 grams solvent, either toluene or octane (both reagent grade, Aldrich Milwaukee, WI) as indicated in Table 2 below, and 6.16 grams of perfluorooctanesulfonic acid catalyst, prepared as described above. Prior to use, the solvents were dried over 4 angstrom molecular sieves. The catalyst slurry was heated to 50°C. Piperylene concentrate (Naphtha Petroleum 3 "Piperylenes" Lyondell Petrochemical Company, Houston, TX), 140 grams, was added to the nitrogen purged reaction flask via the dropping funnel over 15 minutes maintaining the 50°C reaction temperature with external cooling or heating as needed. Prior to use, the piperylene concentrate was dried over activated alumina (Fischer 8-16 mesh). The reaction solution was stirred at 50°C for a total reaction time of 4 hours. Upon completion of the reaction time, the catalyst was converted back to the potassium salt by treating the reaction solution with a 30% solution of potassium hydroxide for 15 minutes. The catalyst was reclaimed by vacuum filtration from the resin solution at room temperature. The reaction flask and catalyst filter cake were then rinsed with approximately 100 milliliters of toluene. After catalyst filtration, the resin oil was placed in a round-bottom flask which was fitted with a distillation head with an adaptor for an inlet tube, thermometer, and attached to a condenser and receiving flask. The resin oil was heated to 235°C with a nitrogen purge followed by a steam purge at 235-245°C to remove light oil products. The steam purge was continued until less than 1 ml of oil was collected per 100 ml of steam condensate or until 1000 ml of steam condensate was collected. The steam purge was followed by a nitrogen purge at 235°C to remove water from the remaining resin. The resins produced have the properties listed in Table 2. TABLE 2 EXAMPLE 6 The following example illustrates the use of reclaimed perfluorooctane sulfonic acid as a catalyst for the polymerization of piperylene concentrate, a C5 monomer feed. The recovered potassium salts from Examples 3-5 were converted back to the perfluorooctanesulfonic acid using the procedures discussed in Examples 3-5. The polymerization was carried out according to the procedures outlined in Examples 3-5 with the following modifications. The flask was charged with 14 grams of toluene and 5.7 grams recovered perfluorooctanesulfonic acid and heated to 50°C for 4 hours. The resin produced has the following properties. Catalyst Reclaimed Perfluorooctanesulfonic Acid Loading 17 wt% on monomer Solvent toluene Yield 18% Softening Point (R&B) 49°C MW - SEC Mn 650 Mw 730 Mz 850 PD 1.1 EXAMPLES 7-13 These examples illustrate the use of perfluorosulfonic acid resins as solid catalysts for the polymerization of piperylene concentrate, a C5 monomer feed. A 500 milliliter three neck flask was equipped with an overhead stirrer, reflux condenser, gas inlet and outlet ports, a thermometer and a dropping addition funnel. The flask was charged with 60 grams solvent. For Examples 7, 8, 10, 11, and 13, the solvent was toluene, and for Examples 9 and 12 the solvent was chlorobenzene (both solvents being reagent grade, Aldrich Milwaukee, WI). Prior to use, the solvents were dried over 4 angstrom molecular sieves. In addition to solvent, the reaction flask was charged with 10 grams of a perfluorosulfonic acid resin catalyst ("Nafion NR50", DuPont, Wilmington, DE, powder or extrudate as indicated in Table 3 below). The catalyst slurry was stirred 1 to 2 hours at room temperature prior to heating to the desired reaction temperature. Piperylene concentrate (Naphtha Petroleum 3 "Piperylenes" Lyondell Petrochemical Company, Houston, TX), 140 grams, was added to the nitrogen purged reaction flask via the dropping addition funnel over 15 minutes maintaining the desired reaction temperature with external cooling or heating as needed. Prior to use, the piperylene concentrate was dried over activated alumina (Examples 7, 8, and 10) or 4 angstrom molecular sieves (Examples 9, 11, 12, 13). The reaction solution was stirred at the reaction temperature for 3-5 hours after the monomer addition was complete. Upon completion of the reaction time, the resin solution was separated from the perfluorosulfonic acid resin catalyst by vacuum filtration at room temperature. After catalyst filtration, solvents and volatile components were removed on a rotary evaporator by heating up to 125°C at 3 mm Hg. As indicated in Table 3, if sufficient product remained after removal of solvent and volatile components, the resin oil was placed in a round-bottom flask which was fitted with a distillation head with an adaptor for an inlet tube, thermometer, and attached to a condenser and receiving flask. The resin oil was heated to 235°C with a nitrogen purge followed by a steam purge at 235-245°C to remove light oil products. The steam purge was continued until less than 1 ml of oil was collected per 100 ml of steam condensate or until 1000 ml of steam condensate was collected. The steam purge was followed by a nitrogen purge at 235°C to remove water from the remaining resin. The products which steam distilled were isolated and analyzed as oils. The resins produced have the properties listed in Table 3. Regarding the below listed yields, the "steam resid." yield refers to the yield of steam stripped resin based on monomer weight and "heavy oil" refers to the amount of oil collected based on monomer weight. TABLE 3 1. Samples were not steam stripped. COMPARATIVE EXAMPLES 14-16 These examples illustrate the polymerization of piperylene concentrate, a C5 monomer feed, with styrene/divinylbenzene sulfonic acid resins. A 500 milliliter three neck flask was equipped with an overhead stirrer, reflux condenser, gas inlet and outlet ports, a thermometer and a dropping addition funnel. The flask was charged with 60 grams toluene (reagent grade, Aldrich Milwaukee, WI) and 5 or 10 grams of a styrene/divinylbenzene sulfonic acid resin catalyst, as indicated in Table 4 ("Amberlyst 1010", "Amberlyst 36(dry)", or "Amberlyst 35(dry)", available from Rohm and Haas, Philadelphia, PA), which catalyst had been calcined at 100°C under vacuum (2-5 mm Hg) for 6 hours. Prior to use, the solvent was dried over 4 angstrom molecular sieves. The catalyst slurry was stirred overnight at room temperature to swell the catalyst. Piperylene concentrate (Naphtha Petroleum 3 "Piperylenes" Lyondell Petrochemical Company, Houston, TX), 140 grams, was added to the nitrogen purged reaction flask via the dropping addition funnel over 15 minutes maintaining the desired reaction temperature with external heating as needed to maintain a reaction temperature of 50°C. Prior to use, the piperylene concentrate was dried over activated alumina. The reaction solution was stirred at 50°C for 5 hours after the monomer addition was complete. The resulting resin solution was separated from the sulfonic acid resin catalyst by vacuum filtration at room temperature. After catalyst filtration, solvents and volatile components were removed on a rotary evaporator by heating up to 125°C at 1 mm Hg. The resins produced have the properties listed in Table 4. TABLE 4 EXAMPLES 17 AND 18 These examples illustrate the use and reuse of triflic acid on clay as a catalyst for the polymerization of piperylene concentrate, a C5 monomer feed. A 500 milliliter three neck flask was equipped with an overhead stirrer, reflux condenser, gas inlet and outlet ports, a thermometer and a dropping addition funnel. The flask was charged with 60 grams toluene (reagent grade, Aldrich Milwaukee, WI) and 15 grams of a 0.1 wt% triflic acid on clay catalyst (United Catalyst, Louisville, KY) which had been calcined at 250°C under a dry nitrogen purge for 1 hour. Prior to use, the solvent was dried over 4 angstrom molecular sieves. The catalyst slurry was heated to 50°C with stirring. Piperylene concentrate (Naphtha Petroleum 3 "Piperylenes", Lyondell Petrochemical Company, Houston, TX), 140 grams, was added to the nitrogen purged reaction flask via the dropping addition funnel over 15 minutes maintaining a 50°C reaction temperature.
