摘要：
Described herein is an oily, transparent reaction product which is prepared by heat treating at 110.degree.-220.degree. C. a dicyclopentadiene and a vinyl aromatic compound. This reaction product can be polymerized by ring-opening in presence or absence of a norbornene monomer to produce a thermoset polymer. Freezing point of the reaction product is below 10.degree. C.
