Zusammenfassung:A polymeric composition of polymerized 1,1-disubstituted alkene compounds, which has a weight average molecular weight of about 20,000 daltons or more. The one or more 1,1-disubstituted alkenes include a compound having a first hydrocarbyl group bonded or through an oxygen atom and a second hydrocarbyl group bonded to the other carbonyl group through direct bond or through an oxygen atom. The compounds can be polymerized 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.
