Light Resistance and Weatherability of Acrylonitrile-CR-Methyl Methacrylate Graft Copolymer

초록

용매 존재하에서 benzoyl peroxide(BPO)를 개시제로 사용하여 폴리 클로로프렌(CR)에 acrylonitrile(AN)과 methyl methacrylate(MMA)를 그라프트 공중합하였다. 합성한 AN-CR-MMA 그라프트 공중합체의 내광성과 내후성을 Fade-o-Meter와 Weather-o-Meter로써 측정하고 색차변화(ΔE)로써 이들을 고찰하였다. 그라프트 공중합체의 내광성과 내후성에 미치는 중합조건의 영향을 고찰한 결과 [AN]/[MMA]의 몰비가 증가할수록, toluene을 용매로 사용하였을 때와 반응온도 80℃에서 그라프팅 효율의 증가로 가장 좋은 내광성과 내후성을 보였다. AN-CR-MMA 그라프트 공중합체의 이들 물성은 CR에 비해 크게 향상되는 것으로 나타났다.

The graft copolymerization of acrylonitrile(AN) and methyl methacrylate(MMA) onto polychloroprene(CR) were carried out in a solvent with benzoyl peroxide(BPO) as an initiator. The effects of the reaction conditions such as mole ratio of AN to MMA, reaction temperatures and used solvents were examined in relation to the light resistance and the weatherability of the graft copolymers. It was concluded that the light resistance and weatherability of the graft copolymer were greatly improved compared with those of CR.
