Abstract	비닐요소(VU)와 초산비닐(VAc)를 라디칼혼성중합하고 VU-VAc혼성중합체를 methanolysis하여 요소기와 히드록시기를 가지는 수용성고분자인 VU-비닐알코올(VA)혼성중합체를 합성하였다. VU는 비닐중합성을 나타내며 이 결과는 Nozakura등의 보고와 일치한다. 수용액중에서 30몰%정도 이상 VU의 조성을 가지는 VU-VA혼성중합체의 Huggins정수는 대단히 큰 값으로 관측되었다. 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.
