Abstract:
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.
