PROCESS FOR PRODUCING HYDROGENATED C9 PETROLEUM RESIN AND HYDROGENATED C9 PETROLEUM RESIN OBTAINED BY THE PROCESS

摘要

Disclosed is a process for preparing ahydrogenated C9 petroleum resin, the process comprisinghydrogenating a C9 petroleum resin obtained bypolymerizing polymerizable monomers of a C9 fraction usinga non-phenolic Friedel-Crafts catalyst in the presence orabsence of a non-phenolic molecular weight modifier. Thehydrogenated C9 petroleum resin obtained according to thepresent invention retains the characteristics of knownhydrogenated C9 petroleum resins and has high thermalstability, good light resistance, and remarkably lowfluorescence.
