Abstract	N-acryloylpyrrolidone과 acrylonitrile을 혼성중합시켜 각 단위체의 반응성비를 구한 결과 생성되는 혼성중합체는 pyrrolidone이 음이온 중합에 매우 좋은 개시제임을 알 수 가 있었다. (r1 = 0.43과 r2 = 1.56) 그리고 그 혼성중합체를 개시제로 하여 그라프트된 nylon-4를 합성하여 중합속도 상수를 구했으며, 그에 따르는 여러 인자들의 효과를 관찰하였다. 그 결과 중합속도 상수로 40℃에서 2.82×10 ³(l/mole, min)와 50℃에서 2.93×10³(l/mole, min)을 얻었다. The copolymerization of N-acryloylpyrrolidone and acrylonitrile was performed in N,N'-dimethylformamide at 50℃ and monomer reactivity ratio was obtained by using IR working curve and Fineman and Ross equation. (r1 = 0.43, r2 = 1.56) It is found that resulting copolymer is good polymeric initiator for anionic graft copolymerization of 2-pyrrolidone. Graft copolymers with polybutylamide (nylon-4) grafts onto poly(NAP-Co-AN) backbone were synthesized and the various effects on the graft copolymerization of 2-pyrrolidone were examined. The rate constants (Kp) of graft anionic polymerization at 40 and 50℃ were 2.82×10 and 2.93×10(l/mole, min), respectively.
