SOLVENT-FREE PROCESS FOR MAKING HIGH MOLECULAR WEIGHT TERPOLYMERS OF MALEIC ANHYDRIDE, C1-C4 ALKYL VINYL ETHER AND ISOBUTYLENE, AND DENTURE ADHESIVE AND DENTIFRICE COMPOSITIONS CONTAINING SUCH TERPOLYMERS

摘要

This invention relates to high molecular weight terpolymers of maleic anhydride, C1-C4 alkyl vinyl ethers and isobutylene, and to a solvent-free process for making such terpolymers, which are particularly useful in denture adhesive and dentifrice compositions.
