Abstract

The invention relates to functionalized polymers including homopolymers and copolymers and their uses in industrial applications and in agricultural applications. In particular, the homopolymers and copolymers may be, for example, used in polymer blends, used as nutritives and in feed compositions, and used in combination with a pharmaceutical or nutritive.

Claims

1. A process for forming a homopolymer or copolymer having an average molecular weight above about 800 Da and a repeat unit comprising Formula (I), the process comprising contacting monomers comprising Formula (V):

2. The process of claim 1, wherein the acid catalyst is stannous octoate.

3. The process of claim 1, wherein dehydration comprises azeotropic distillation.

4. The process of claim 1, where in the homopolymer or copolymer produced contains less than 2% of a free monomer.

5. The process of claim 1, where in the homopolymer or copolymer produced contains less than 1% of a free monomer.

6. The process of claim 1, where in the homopolymer or copolymer produced contains less than 0.5% of a free monomer.

7. The process of claim 1, wherein Z is sulfur, R⁶ is methyl, n is 1, and R⁷ is not present.

8. A process for preparing a homopolymer having an average molecular weight above about 800 Da the process comprising contacting monomers comprising Formula (V):

9. The process of claim 8, wherein the acid catalyst is stannous octoate.

10. The process of claim 8, wherein dehydration comprises azeotropic distillation.

11. The process of claim 8, where in the homopolymer or copolymer produced contains less than 2% of a free monomer.

12. The process of claim 8, where in the homopolymer or copolymer produced contains less than 1% of a free monomer.

13. The process of claim 8, where in the homopolymer or copolymer produced contains less than 0.5% of a free monomer.

14. The process of claim 8, wherein Z is sulfur and R⁶ is methyl.

15. A process for preparing a homopolymer having an average molecular weight above about 800 Da the process comprising contacting monomers comprising Formula (V):

16. The process of claim 15, wherein dehydration conditions comprise azeotropic distillation.

17. The process of claim 15, wherein stannous octoate is added after azeotropic distillation under nitrogen at a temperature of about 120°

C. to about 150°
