SUBSTITUTED ACETYLENES AS RATE MODERATORS FOR RING-OPENING METATHESIS POLYMERIZATION

摘要

A hydrocarbon-substituted acetylene, e.g.,phenylacetylene, hexyne-1 or hexyne-2, is used to moderatethe catalyst activation characteristics of an alkylaluminumcompound in the ring-opening metathesis polymerization ofdicyclopentadiene and other polycyclic cycloolefins.
