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 monomer, 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° C. to 170° 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.
A process for making a hydrocarbon resin, comprising polymerizing a feed stream comprising at least one member selected from the group consisting of pure monomer comprising C5 or higher monomer, and C5 monomers, and C9 monomers in the presence of a fluorinated solid acid catalyst to produce a hydrocarbon resin, wherein the fluorinated solid acid catalyst comprises at least one member selected from the group consisting of perfluoroalkanesulfonic acid, perfluoroalkanesulfonimide, lanthanide perfluoroalkanesulfonate, aluminum perfluoroalkanesulfonate with each alkane group containing at least 2 carbons, lanthanide triflate with acid promoter, and supported fluorinated solid acid which is supported on one of clay, silica, silica-alumina, and zeolite, and wherein the hydrocarbon resin has a number average molecular weight (Mn) ranging from about 400 to 2000 for feed streams comprising at least pure monomer, about 400 to 2000 for feed streams comprising at least C5 monomers, and about 400 to 1200 for feed streams comprising at least C9 monomers.
A process for making a hydrocarbon resin, comprising polmerizing a feed stream comprising C9 monomers in the presence of a fluorinated solid acid catalyst to produce a hydrocarbon resin, wherein the fluorinated solid acid catalyst is added to the feed, and wherein the hydrocarbon resin has a number average molecular weight (Mn) of about 400 to 1200, a weight average molecular weight (Mw) of about 500 to 2000, a Z average molecular weight (Mz) of about 700 to 6000, and a polydispersity (PD) as measured by Mw/Mn between about 1.2 and 3.5, where Mn, Mw, and Mz are determined by size exclusion chromatography (SEC).
