Title:

PROCESS FOR PRODUCING HYDROGENATED C¿9? PETROLEUM RESIN AND HYDROGENATED C¿9? PETROLEUM RESIN OBTAINED BY THE PROCESS

Document Type and Number:

WIPO Patent Application WO/2000/018815

Kind Code:

A1

Abstract:

A process for producing a hydrogenated C¿9? petroleum resin which comprises polymerizing polymerizable monomers contained in a C¿9? fraction using a non-phenolic Friedel-Crafts catalyst in the presence or absence of a non phenolic regulator and hydrogenating the resultant C¿9? petroleum resin. Thus, a hydrogenated C¿9? petroleum resin is obtained which has the intact properties inherent in hydrogenated C¿9? petroleum resins and is excellent in stability to heating and light resistance and extremely reduced in fluorescent color development.
