  • Patent number: 10633566
    Abstract: Disclosed is a block copolymer having a first polymer block including a first primary monomer that is a 1,1-disubstituted alkene compound, wherein the first primary monomer is present at a concentration of about 50 weight percent or more, based on the total weight of the first polymer block, the first polymer block covalently bonded to a second polymer block including a second primary monomer different from the first primary monomer, wherein the second primary monomer is present at a concentration of about 50 weight percent or more, based on the total weight of the second polymer block. Also disclosed is a polymer comprising at least one monomer of a 1,1-disubstituted alkene compound having a weight average molecular weight of about 3000 daltons or more, wherein the polymer is substantially free of a melting temperature and is substantially free of a glass transition temperature of about 15° C. or more.

  • Patent number: 10184073
    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.
