Abstract

The present invention relates to a process for the production of 3-mono or 3,5-disubstituted-4-acetoxystyrene wherein the 3- or 3,5-substitution is independently C.sub.1 to C.sub.10 alkyl, chlorine, bromine, iodine, --NO.sub.2, --NH.sub.2, or --SO.sub.3 H, a process for its polymerization, hydrolysis, and use in a variety of compositions.
