Abstract
스티렌과 메틸아크릴레이트(methyl acrylate, MA)를 원자라디칼이동 중합(atom radical transfer polymerization, ATRP) 에서 주요한 중합공정 조건인 투입되는 MA 몰분율, 중합 온도, 중합 시간이 미치는 영향을 조사하였다. MA 몰분율이 증가할수록 분자량은 증가하고 중합시간이 3시간일 때 중합용액의 초기 모노머 몰 비와 생성되는 고분자의 조성비가 거의 선형 관계를 갖는다. 중합시간이 증가함에 따라 공중합체의 분자량은 증가하고, 공중합체의 MA 조성비가 감소함을 알 수 있다. 이를 통해 스티렌-MA 공중도 ATRP의 리빙 라디칼 중합 특징을 보이고 있음을 알 수 있다. 중합 온도가 증가함에 따라 공중합체의 분자량은 크게 증가하고, 특히 110 ℃의 고온에서 공중합체 내에 MA 조성비가 크게 증가함을 볼 수 있다.
Investigated was the effect of the crucial polymerization conditions such as methyl acrylate(MA) mole fraction in feed, polymerization temperature and time on Atom Radical Transfer Polymerization(ATRP) behavior of styrene and methyl acrylate(MA). As MA mole fraction in feed increased, molecular weight(MW) of the resulting copolymer increased. At polymerization time of 3 hrs the composition of MA in the resulting copolymer was shown to have a linear relationship with the mole fraction of MA in feed. MW was increased and the composition of MA in copolymer_x000D_
was decreased as the polymerization time increased, showing the characteristics of ATRP. MW was also increased as polymerization temperature increased, and the composition of MA in copolymer was shown to be increased drastically at polymerization temperature of 110℃ .
