Abstract

The quaternary random copolyesters of poly (butylene glutarate-co-adipate-co-succinate-co-terephthalate)(PBGAST) were synthesized and charaterized by $^1H-NMR$ spectrometry, DSC method, and X-ray diffractometry. Thus the melting point trends and crystallization behaviors of PBGAST copolyesters were obviously depended on terephthalate content in copolymers as well as reaction condition.

사성분계 랜덤 공중합체인 poly(butylene glutarate-co-adipate-co-succinate-co-terephthalate)(PBGAST)를 합성하고 $^1H-NMR$ 분광분석법, 시차주사열량분석법(DSC) 및 X-선회절법 등을 시행하였다. PBGAST 공중합체의 융점거동과 결정화거동은 반응조건 뿐 만 아니라 공중합체내 terephthalate 단위의 함량에도 의존하였다.
