Abstract
The miscibiliity of two kinds of polymers, polyurethane(PU) elastomers and Pu-poly(butylene terephthalate) multiblock copolymers(BC''s), which have the common unit of PU block fronts diphenylmethane -4,4-diisocyanate and 1,4-butanediol was studied. The miscibility was increased with the content of PU block in PU elastomer, which was observed from the glass transition temperatures by DSC and the morphologies by scanning electron microscopy.

Diphenylmethane-4, 4''-diisocyanate와 1, 4-butanediol이 반응한 polyurethane(PU)블록을 공통 구조로 갖는 PU 탄성체와 PU-poly(butylene terephthalate) multiblock 공중합체(BC)의 상용성을 두 고분자의 구조를 변화시키면서 조사하였다. PU 탄성체 내의 PU블록의 함량이 많을수록 BC와의 상용성이 증가하였으며 이를 Tg변화와 주사 전자 현미경으로 관찰한 morphology로 부터 확인할 수 있었다.
