Abstract

본 발명은 다음 구조식(Ⅰ)의 디이미드-디올 단량체, 에틸렌글리콜 및 코모노머로 테레프탈산 또는 그 반응성 유도체를 반응시켜서 신규의 폴리에스테르-이미드 공중합체를 제공하는 것이며,The present invention is to provide a novel polyester-imide copolymer by reacting terephthalic acid or a reactive derivative thereof with the diimide-diol monomer, ethylene glycol and comonomer of the following structural formula (I),

이렇게 제조된 신규의 폴리에스테르-이미드 공중합체는 대단히 우수한 내열성 및 가스베리어성이 우수하여 식품 및 비식품의 포장용기 또는 필름으로서 사용될 수 있다.The novel polyester-imide copolymer thus prepared is excellent in heat resistance and gas barrier properties and can be used as a packaging container or film for food and non-food.
