Abstract
Hydroxy-functional allyl terpolymers are disclosed. The terpolymers comprise recurring units of an allyl ester, an allylic alcohols or propoxylated allylic alcohol, and a vinyl monomer. The high hydroxyl group content and favorable solubility characteristics make the terpolymers easy to formulate into many polymer products, including polyurethanes, polyesters, melamines, alkyds, uralkyds, and other thermoset polymers.
Claims6
A terpolymer which comprises recurring units of:
- (a) an allyl ester of the formula CH.sub.2 .dbd.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;
- (b) a propoxylated allylic alcohol of the formula
- CH.sub.2 .dbd.CR'--CH.sub.2 --(A).sub.n --OH
- in which A is an oxypropylene group, R' is selected from the group consisting of hydrogen and C.sub.1 -C.sub.5 alkyl, and n, which is the average number of oxypropylene groups in the propoxylated allylic alcohol, has a value less than or equal to 2;
- and
- (c) a vinyl monomer selected from the group consisting of vinyl aromatic monomers, vinyl halides, vinyl ethers, acrylonitrile, methacrylonitrile, acrylamide, methacrylamide, acrylates, methacrylates, and vinyl esters;
- wherein the terpolymer 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.
