Coatings containing polyester macromers containing 1,1-dicarbonyl-substituted 1 alkenes
First Claim
1. A composition comprising a) one or more 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;
- and b) one or more polymers having pendant Michael Addition donor groups;
wherein the diols used to prepare the polyester macromers comprise diols with aliphatic backbones that are branched or diols with cycloaliphatic backbones.
