Abstract
The graft polymerization of methyl methacrylate (MMA) onto chitin initiated by ceric ammonium nitrate (CAN) was investigated. The grafted-polymer was identified by using IR spectroscopy and electron micrographs. No grafting was observed in the usual organic solvents such as formic acid and methanol. It was found that water was essential to the grafting. The optimum conditions on the weight increase, the percentage of grafting. and the degree of grafting were determined by varing media, reaction temperature, reaction time, monomer concentration, and initiator concentration.

Ceric ammonium nitrate (CAN)을 개시제로 하여 chitin에 methyl methacrylate(MMA)를 그라프트 공중합하였다. 그라프트 공중합체의 화인은 IR 스펙트럼과 전자현미경으로 행하였다. Formic acid, methanol과 같은 유기 용매를 사용하였을 경우에는 그라프트 공중합체가 형성되지 않았고, 물이 그라프트 공중합에 있어서 필수적인 용매임을 알 수 있었다. 중량 증가율, 그라프트율 등에 대한 반응 온도, 반응 시간, 단량체의 농도, 개시제의 농도 등의 최적 조건을 구하였다.
