A process for the preparation of solvent-free, fine white powder of high molecular weight, copolymers of maleic anhydride and a c1 - c4 alkyl vinyl ether without odor or taste

摘要

Solvent-free, the white powders of high molecular weight copolymeers of maleic anhydride and C1-C4 alkyl vinyl ethers, which are particularly useful as starting materials for denture adhesives. A solvent-free process for making such copolymers also is described.
