  • Patent number: 9745413
    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.

  • Publication number: 20170240657
    Abstract: The present teachings show that it is possible to polymerize 1,1-disubstituted alkene compounds in a solution (for example using one or more solvents). Polymerization of 1,1-disubstituted alkene compounds in a solution provides opportunities to better control the polymerization compared with bulk polymerization. The solution polymerization techniques can be employed for preparing homopolymers, copolymers (e.g., random copolymers), and block copolymers.
