SOLVENT-FREE, FINE WHITE POWDERS 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.
