Abstract

PURPOSE: To obtain a wide-MW distribution hydrocarbon resin without forming gel- like mass, by adding, to the reaction system, a linear conjugated diolefin in the course of polymerization of a monomer mixture containing the linear conjugated diolefin and a monoolefinically unsaturated hydrocarbon monomer.
CONSTITUTION: In the cationic polymerization of a monomer mixture containing a 4W5C linear conjugated diolefin (such as 1,3-pentadiene or isoprene) and a 4W10C monoolefinically unsaturated hydrocarbon copolymerizable therewith, such as isobutylene or 1-butene, a hydrocarbon resin having a controlled MW distribution is produced by polymerizing previously a portion of said monomer mixture, adding and polymerizing said linear conjugated diolefin and adding and polymerizing the remaining portion of the monomer mixture.
