Abstract
자유라디칼 telomerization 반응을 이용하여 스티렌-메타크릴산메틸 block 혼성중합체 (PS-b-PMMA)를 합성하였다. AIBN을 개시제로 사용하여 CCl4로 스티렌을 telomerization시킨 다음 생성된 중합체의 CCl3 말단기를 macrotelogen으로 사용하여 AIBN 개시에 의해 메타크릴산 메틸을 다시 telomerization하여 스티렌-메타크릴산메틸 block 혼성중합체를 얻었다. Macrotelogen의 농도, 단위체의 농도, macrotelogen의 분자량, 반응온도 및 용매의 농도가 block 혼성중합체생성에 미치는 영향을 조사하였다. 반응조건을 조절하여, PMMA가 약 10무게%까지 포함된 block 혼성중합체를 얻었다.

Poly (styrene-b-methyl methacrylate) (PS-b-PMMA) was synthesized by free radical telomerization: the telomerization of styrene with CCl4 by using AIBN as initiator followed by a second telomerization of methyl methacrylate using CCl3 end group of the resulting polymer as the macrotelogen, with AIBN initiation, gave the styrene-methyl methacrylate block copolymer. The effects of the concentration of the macrotelogen, the concentration of monomer, the molecular weight of the macrotelogen, the reaction temperature and the concentration of the solvent on the formation of the block copolymer were investigated. Block copolymers containing up to 10 weight percent PMMA were obtained by adjusting the reaction conditions.
