Abstract

This invention provides reactive, flexible, water-resistant hydroxyethylpyrrolidone methacrylate/glycidyl methacrylate copolymers, or hydroxyethylpyrrolidone methacrylate/glycidyl methacrylate/-(Methacroyloxyglyceryl-Cellulosic) block copolymers. This invention provides hydroxyethylpyrrolidone methacrylate/glycidyl methacrylate copolymers having the structure: wherein x and y are mole %, the sum equals to 100, and wherein said copolymer is prepared by precipitation polymerization. The copolymer is useful in a wide variety of compositions.

Claims (5)

1. A hydroxyethylpyrrolidone methacrylate/glycidyl methacrylate copolymer having a structure:

wherein x and y are mole %, the sum equals to 100; and

wherein said copolymer is prepared by precipitation polymerization.

2. The copolymer according to claim 1 , wherein x ranging from about 5 to about 98 and y is ranging from about 2 to about 95.

3. The copolymer according to claim 1 , wherein x is ranging from about 10 to about 90 and y is ranging from about 10 to about 90.
