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.

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, andX-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.
