Title:
PROCESS FOR PRODUCING N-PYRROLIDONE GRAFT POLYMER COMPOSITION AND N-PYRROLIDONE GRAFT POLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2007/037376
Kind Code:
A1
Abstract:
A process for producing an N-vinylpyrrolidone graft polymer which can have an improved degree of vinyl monomer grafting and can hydrophilize the surface of a plastic base, etc. The process for N-vinylpyrrolidone graft polymer production comprises the step of reacting an N-vinylpyrrolidone polymer with a vinyl monomer. In the process for producing an N-vinylpyrrolidone graft polymer, the N-vinylpyrrolidone polymer to be reacted as a raw material is regulated so as to have a 2-pyrrolidone content of 10,000 ppm or lower.
