Abstract

The present disclosure relates to compositions comprising a copolymer that includes a first monomer and a second monomer that is different from the first monomer, wherein both the first and second monomer are selected from the group consisting of 3-sulfopropyl acrylate potassium salt, sodium acrylate, N-(tris(hydroxyl methyl)methyl)acrylamide, and 2-acrylamideo-2-methyl-1-propane sulfonic acid. The present disclosure further relates to methods for preparing the copolymer compositions and shaped articles comprising the copolymers.

Claims (7)

1. A suture comprising at least one fiber and a coating on at least a portion of the fiber, the coating containing a copolymer that includes a first monomer and a second monomer that is different from the first monomer, wherein both the first and second monomer are selected from the group consisting of 3-sulfopropyl acrylate potassium salt, sodium acrylate, N-(tris(hydroxyl methyl)methyl)acrylamide, and 2-acrylamido-2-methyl-1-propane sulfonic acid.

2. A suture as in claim 1 wherein the coating further comprises a therapeutically beneficial compound.

3. A sutures as in claim 1 wherein the coating further comprises a contrasting agent.

4. A suture as in claim 1 wherein the coating further comprises a radioactive substance.

5. A suture as in claim 1 wherein the coating further comprises a dye.

6. A suture as in claim 1 , wherein the coating further comprises a crosslinking agent.

7. A suture as in claim 1 , further comprising a hydrophilicity modifying monomer wherein the hydrophilicity modifying monomer is selected from the group consisting of methylmethacrylate, butylacrylate, cyclohexylacrylate, styrene, styrene sulphonic acid, etc.
