Abstract

AbstractCopolymers were prepared by ester interchange of polyvinylalcohol with ethyl acetoacetate, ethyl benzoylacetate, and ethyl 4‐nitrobenzoylacetate. Reaction of ethyl 2,4,6‐trimethylbenzoylacetate with polyvinylalcohol yielded a homopolymer. The polymers functioned as chelate ion exchangers. Ion exchange capacities were determined for the polymer derived from polyvinylalcohol and ethyl acetoacetate.
