PROCEDE D'OBTENTION DES TETRAPOLYMERES OLEFINIQUES AMORPHE

摘要

Vulcanizable olefin tetrapolymers are described which are comprised of ethylene, an alpha-olefin having at least three carbon atoms, at least one conventional terpolymer such as endo- and exo-dicyclopentadiene, and a minor amount of a polycyclic polyene represented by the formula A-(CH2)n-B, wherein A is a radical consisting of or containing at least one cyclohexane ring with or without an endomethylene bridge, B is a cyclodiene radical and n is a number ranging from 0 to 5.
