Abstract
Disclosed is a process for preparing a hydrogenated C petroleum resin, the process comprising hydrogenating a C petroleum resin obtained by polymerizing polymerizable monomers of a C fraction using a non-phenolic Friedel-Crafts catalyst in the presence or absence of a non-phenolic molecular weight modifier. The hydrogenated C petroleum resin obtained according to the present invention retains the characteristics of known hydrogenated C petroleum resins and has high thermal stability, good light resistance, and remarkably low fluorescence.
