Abstract:
A process for the preparation of the addition product of a linear telechelic difunctional unsaturated polymer containing terminal functional reactive groups other than vinyl groups, comprising simultaneously reacting (a) 1,5-cyclooctadiene, (b) a difunctional ester of 2-butene-1,4-diol, wherein the functional groups are selected from the group consisting of hydroxyl, ester, alcohol, amine, acid, acyl halide, ketone, aldehyde, borane, amide, acid anhydride, ether, imide, halogen atom, alkyl, aryl and substituted aryl groups of up to about 30 carbon atoms, and mixtures thereof, and (c) H.sub.2, in the presence of at least one olefin metathesis catalyst to prepare an addition product of a linear difunctional unsaturated polymer, wherein H.sub.2 adds to a carbon--carbon double bond under ROMP reaction conditions.
