  • Solution polymers including one or more 1,1-disubstituted alkene compounds, solution polymerization methods, and polymer compositions
    Patent number: 9676875
    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 an 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.

  • Emulsion polymers including one or more 1,1-disubstituted alkene compounds, emulsion methods, and polymer compositions
    Patent number: 9637564
    Abstract: The present teachings show that it is possible to polymerize 1,1-disubstituted alkene compounds in an emulsion (for example using a water based carrier liquid), despite the possible reactions between the monomer and water. Polymerization of 1,1-disubstituted alkene compounds in an emulsion provides opportunities to better control the polymerization compared with bulk polymerization. The emulsion polymerization techniques can be employed for preparing homopolymers, copolymers (e.g., random copolymers), and block copolymers.
