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.

First claim

What is claimed is:

1. 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.

2. The copolymer of claim 1 , wherein the polymer is a star polymer having 3 or more arms.

3. The copolymer of claim 1 , wherein the copolymer has a linear backbone with long chain branching distributed along the backbone.

4. The copolymer of claim 1 , wherein the copolymer includes about 0.002 weight percent to about 2 weight percent of a multifunctional monomer.

5. The polymer of claim 1 , wherein the polymer forms a block copolymer.

6. The polymer of claim 1 , wherein the polymer is a star polymer having 5 or more arms.

7. The polymer of claim 1 , wherein the Tg of the homopolymer of the first polymer is about 35° C. or more.

8. The copolymer of claim 1 including about 50 weight percent or more of the first monomer, wherein the polymer has long chain branching, wherein the polymer has one or any combination of the following characteristics:
i) a polydispersity of about 3 or less; or
ii) a weight average molecular weight of about 50,000 or more; or
iii) is in the form of solid particles.

9. 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.

10. The copolymer of claim 9 , wherein the copolymer is a block copolymer.

11. The copolymer of claim 9 , wherein the copolymer has a linear backbone with long chain branching distributed along the backbone.

12. The copolymer of claim 9 , wherein the copolymer includes about 0.002 weight percent to about 2 weight percent of a multifunctional monomer.
