Conversion of solid dicyclopentadiene to a liquid monomer for use in reaction injection molding

摘要

Disclosed are a metathesis-polymerizable mixture containing dicyclopentadiene that is liquid at temperatures below room temperature, containing an oligomer (or mixture of oligomers) of cyclopentadiene that is copolymerizable with dicyclopentadiene such as the trimer, tetramer or pentamer of cyclopentadiene, methods for making the mixture, its use for making copolymers of dicyclopentadiene that have significantly better Tg and heat distortion temperatures than poly(dicyclopentadiene), and the said copolymers themselves.
