| 摘要 |
A hard, infusible, crosslinked polymeric product free from detectable cyclopentadiene odor is obtained by contacting, un- der polymerization conditions, a mixture of Diels-Alder adducts of 4- vinylcyclohexene and cyclopentadiene and Diels-Alder oli- gomers of cyclopentadiene of at least 3 cyclopentadiene units with an olefin methathesis catalyst, preferably a catalyst comprising a di(alkyl-substituted phenoxy) tungsten halide, a triorganotin hydride and, optionally, a boron halide.
