Abstract

N-Vinylurea(VU) was radically copolymerized with vinyl acetate (VAc). VU-vinyl alcohol (VA) copolymer, which is a water-soluble polymer with pendent urea and hydroxyl groups, was synthesized by the methanolysis of the VU-VAc copolymer.VU shows vinyl polymerization, and this result is in agreement with that of Nozakura, et al. Huggins constant for the aqueous solution of the VU-VA copolymer containing more than about 30 mole percent of VU was observed to be a high value.
