Patent ID: 8324334

Claim:
A method for carrying out a catalytic ring-opening metathesis polymerization reaction, comprising contacting (a) at least one olefinic compound selected from an unsaturated diol having a carbon chain length of greater than C 4 , wherein the unsaturated diol is derived from a monoglyceride, a diglyceride, a triglyceride, or a mixture thereof; is derived from a seed oil, or a mixture of seed oils; has the structure of formula (A) wherein, R is an —OH group; r is 1, 2, or 3; and p and q are independently from 0 to 30, provided that at least one of p and q is not zero; is derived from an unsaturated fatty acid, fatty acid ester, or fatty alcohol or a mixture thereof; or is derived from cross metathesis of fatty acids, fatty acid esters, or fatty alcohols or mixtures thereof, with (b) at least one cyclic olefin, in the presence of (c) an alkylidene olefin metathesis catalyst, (d) under conditions effective to allow ring-opening metathesis polymerization of the cyclic olefin, whereby the cyclic olefin polymer formed thereby is terminated with the hydroxyl groups of the unsaturated diol.
