The disclosure relates to polymers including one or more 1,1-disubstitued 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.

Polymers including one or more 1,1-disubstituted alkene compounds and polymer compositions thereof

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&#xb0; C. or more.

Polymers containing a 1,1-disubstituted alkene compound

The disclosure relates to compositions containing 1,1-di-carbonyl-substituted alkene compounds capable of preparing polymers having glass transition temperatures above room temperature.

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.

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).

Polymer and other compounds functionalized with terminal 1,1-disubstituted alkene monomer(s) and methods thereof

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.
