Abstract
Allyl ester copolymers with allylic alcohols and propoxylated allylic alcohols are disclosed. The high hydroxyl group content and favorable solubility characteristics make the allyl ester copolymers easy to formulate into many polymer products, including polyurethanes, polyesters, melamines, alkyds, uralkyds, and other thermoset polymers.
Claims6
A copolymer which consists essentially of recurring units of:
- (a) an allyl ester of the formula CH.sub.2 =CR'-CH.sub.2 -O-CO-R in which R is hydrogen or a saturated linear, branched, or cyclic C.sub.1 -C.sub.30 alkyl, aryl, or aralkyl group, and R' is selected from the group consisting of hydrogen and C.sub.1 -C.sub.5 alkyl;
- and
- (b) an allylic alcohol of the formula CH.sub.2 =CR'-CH.sub.2 -OH in which R' is selected from the group consisting of hydrogen and C.sub.1 -C.sub.5 alkyl;
- wherein the copolymer has an average hydroxyl functionality within the range of about 2 to about 10, and a number average molecular weight within the range of about 300 to about 15,000.
