## 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
