The synthesis of N-acrylylpyrrolidone has been carried out by the reaction of pyrrolidone and acrylylchloride.
The study on the copolymer of N-acrylylpyrrolidone and styrene and graft copolymer of nylon - 4 initiated by polymeric initiator is attempted.
The copolymerization of N-acrylylpyrrolidone and styrene is carried out in benzene.
Monomer reactivity ratio of N-acrylylpyrroljdone and styrene was calculated by Fineman and Ross equation.
It is observed that the copolymer of N-acrylylpyrrolidone and styrene has random distributed acyl-lactam function on the vinyl polymer backbone.
It is found that copolymer of N-acrylylpyrrolidone and styrene is effective as an initiator of anionic polymerization of pyrrolidone with potassium hydroxide as a catalyst.
The highest equillibrium conversion and viscosity are obtained when the concentration of catalyst and initiator was 5.0 and 1.0 mol% at 50℃.
The highest inherent viscosity of grafted nylon - 4 was measured to be 2.2 dℓ/gr and the highest percent graft was 4605%.
새로운 Acrylimide로서 N - acrylypyrrolidone 을 합성하였다.
N - acrylylpyrrolidone 은 N - methacrylyl - lactam 과는 다르게 homopolymerization 을 열적으로도 함을 관찰하였다.
Styrene 과 N - acrylylpyrrolidone 의 공중합시 각 monomer의 reactivity ratio 를 구하였다.
그 결과 생성되는 copolymer 는 pyrrolidone 의 음이온 중합에 적절한 acyl - lactam function 을 가지고 있음을 알았다.
이 copolymer 를 개시제로 하여 graft 된 nylon - 4 를 합성하였으며, 이때 점도는 최고 2.2 였으며, 최고의 percent graft는 4605% 였다.
