Abstract
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.
Claims12
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 and the second monomer includes a styrene, a butadiene, an acrylonitrile, a different 1,1-disubstituted alkene monomer or any combination thereof, wherein when the second monomer is a different 1,1-disubstituted alkene monomer, the first monomer has a structure such that homopolymers of the first monomer have a Tg of about 25° C. or more and the second monomer that is the different 1,1-disubstituted alkene monomer has a structure such that homopolymers of the second monomer have a Tg of about 15° C. or less.

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 and the second monomer includes one or more acrylates, one or more methacrylates, a styrene, a butadiene, an acrylonitrile, a different 1,1-disubstituted alkene monomer or any combination thereof, wherein the copolymer has a polydispersity of about 2.3 or less and when the second monomer is a different 1,1-disubstituted alkene monomer, the first monomer has a structure such that homopolymers of the first monomer have a Tg of about 25° C. or more and the second monomer that is the different 1,1-disubstituted alkene monomer has a structure such that homopolymers of the second monomer have a Tg of about 15° C. or less.
