N - 메틸 치환 열가소성 폴리우레탄의 제조 및 전도도에 관한 연구

Abstract

Segmented polyurethane was synthesized from 4,4`-methylene bis(phenyl isocyanate), butanediol and polyoxytetramethylene glycol with molecular weight 2000 in tetrahydrofuran. In the previous paper, we manufactured the N-methyl substituted polyurethane and observed the morphology and mechanical property as a function of substitution degree. In this study, we observed the thermal, mechanical properties and conductivity as a function of LiClO₄ Concentration in the N-methyl substituted polyurethane.
