  • Patent number: 10308802
    Abstract: The disclosure relates to polymers including one or more 1,1-disubstituted alkene monomers. By employing a plurality of monomers and/or tailored chain structure, polymers having improved combinations of properties are achieved. The polymer may be a copolymer, preferably including two or more 1,1-disubstituted alkene monomers. The polymer may be a homopolymer having a tailored chain structure.

  • Patent number: 10196481
    Abstract: Functionalized compounds including residues of one or more 1,1-disubstituted alkene compounds. Preferably the functionalized compound includes the residue of two or more 1,1-disubstituted alkene compounds, which are spaced apart. The functionalized compound may be produced by a transesterification reaction. The functionalized compounds may be employed in a polymerizable composition and may be used to prepare new polymers, (for example by reacting the alkene group).

  • Patent number: 10087283
    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.
