Abstract
In a process for producing a functionalized polyalkenamer, at least one monomer comprising a monocyclic olefin having at least one pendant alkyl group bonded thereto, wherein the pendant alkyl group has at least two carbon atoms and is substituted with a polar moiety spaced by at least one carbon atom from the monocyclic olefin, is contacted with a polymerization catalyst under conditions effective to effect ring opening polymerization of the monocyclic olefin and produce the functionalized polyalkenamer.
Claims10
A functionalized polyalkenamer comprising repeating units of ethylene, butadiene, and a polar group-substituted α-olefin termonomer, said α-olefin termonomer having at least four carbons and having its polar group spaced by at least one carbon from the polymerizing olefin unit.
A functionalized polyalkenamer comprising repeating units of ethylene, butadiene, and 4-pentenenitrile.
