Polyester macromers containing 1,1-dicarbonyl-substituted 1 alkenes
First Claim
1. A composition comprisingi) from about 10 to about 80 percent by weight of a composition comprising a plurality of polyester macromers containing one or more chains of the residue of one or more diols and one or more diesters wherein the residue of the one or more diols and the one or more diesters alternate along the chain and a portion of the diesters are 1,1-diester-1-alkenes and at least one terminal end comprises the residue of one of the 1,1-diester-1-alkenes and wherein one or more terminal ends may comprise the residue of one or more diols;
- ii) from about 5 to about 40 percent by weight of one or more multifunctional monomers containing the residue of one or more polyols and one or more 1,1-diester-1-alkenes, wherein the multifunctional monomers have substantially all of the hydroxyl groups of the polyols replaced with the 1,1-diester-1-alkenes; and
iii) from about 1 to about 40 percent by weight of one or more 1,1-diester-1-alkenes;
wherein the amounts are based on the weight of the composition.

Abstract
Disclosed are compositions comprising polyester macromers containing in one or more chains the residue of one or more diols and one or more diesters wherein the residue of the one or more diols and the one or more diesters alternate along the chain and a portion of the diesters are 1,1-diester-1-alkenes, and optionally one or more dihydrocarbyl dicarboxylates, and at least one terminal end comprises the residue of one of the 1,1-diester-1 alkenes and wherein one or more terminal ends may comprise the residue of one or more diols. The chains may contain the residue of the one or more diols and one or more diesters comprising one or more diesters 1,1-diester-1 alkenes and optionally one or more dihydrocarbyl dicarboxylates randomly disposed along the chains. Disclosed are methods of preparing the polyester macromers and incorporating them in a variety of polyester containing compositions such as coatings and films.

14. A method comprising:
-
contacting one or more polyols with an equivalents excess of one or more 1,1-diester 1-alkenes in the presence of a transesterification catalyst under conditions such that one or more multifunctional monomers are formed wherein the multifunctional monomers contain the one or more polyols having two or more of their hydroxyl groups replaced with the residue of the one or more 1,1-diester 1-alkenes; and contacting the multifunctional monomers with an additional amount of the one or more polyols, with the proviso that the additional amount of the one or more polyols are diols, or with one or more second polyols which are diols, in the presence of a transesterification catalyst under conditions such that one or more polyester macromers are prepared which contain one or more chains of the residue of one or more diols and one or more 1,1-diester-1-alkenes wherein the residue of the one or more diols and the one or more 1,1-diester-1 alkenes alternate along the chain and at least one terminal end comprises the residue of one of the 1,1-diester-1 alkenes and wherein one or more terminal ends may comprise the residue of one or more diols. - View Dependent Claims (16)
