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.

A copolymer comprising:
- i) from about 2 weight percent to about 98 weight percent of a first monomer;
- and
- ii) from about 2 weight percent to about 98 weight percent of a second monomer;
- wherein the first monomer is one or more 1,1-disubstituted alkene monomers, wherein the 1,1-disubstituted alkene monomer includes a central carbon atom doubly bonded to another carbon atom and further bonded to two carbonyl groups;
- wherein the first monomer has a structure such that homopolymers of the first monomer have a Tg of about 50° C. or more;
- the second monomer has a structure such that homopolymers of the second monomer have a Tg of about 15° C. or less;
- and
- wherein the copolymer has a single glass transition temperature of about −100° C. to about 15° C.;
- and wherein the first monomer corresponds to Formula IIA;
- wherein R1 and R2 are each hydrocarbyl groups that may be the same or different;
- wherein weight percent is based on total weight of the copolymer.
