Abstract
Miscibility of the blends of poly(vinyl methyl ether) (PVME) and copolymers of styrene and p- or m- methylstyrene showing LCST behavior was investigated by Fourier Transform Infrared (FTIR) spectroscopy. In this work, we synthesized poly(styrene-co-p-methylstyrene) and poly(styrene-co-m-methylstyrene) by radical polymerization, in which the component of styrene is 10 and 20wt.%. The miscibility of the styrene/styrene derivative copolymers with PVME, based on the Hsu's criterion, was poorer than for polystyrene/PVME. However, poly(styrene-co-p-methylstyrene) showed better miscibility than poly(styrene-co-m-methylstyrene). The miscibility decreased with increasing compositions of styrene derivatives in the copolymers and PVME concentrations. This behavior is in good agreement with the results obtained by light scattering and fluoresence spectroscopy.

저임계용액온도(LCST)를 보인은 범위 내에서의 styrene과 p- 및 m-메틸스티렌 공중합체과 poly(vinyl methyl ether)(PVME)와의 상용성을 FT-IR 분광 분석법에 의해 조사하였다. 본 연구를 위해 스티렌 유도체의 함량이 feed ratio로 10 및 20wt.%가 되도록 중합시킨 공중합체를 사용하였다. Hsu's Criterion 에 의해 PVME와의 상용성은 두 공중합체 모두 폴리스티렌보다는 나쁜 상용성을 보였으나, poly(styrene-co-p-methylstyrene)이 poly(styrene-co-m-methylstyrene)보다 양호한 상용성을 보임을 알았다. 또한 공중합체내 스티렌유도체와 PVME의 함량이 증가할수록 상용성은 감소하였다. 이 결과는 광산란법과 fluorescence 분광 분석법에 의해서도 확인되었다.
