Abstract

본 발명은 내구성이 향상된 내열폴리에스테르 용기를 제공하는 것으로 디카르본산 성분단위에 테레프탈산 단위를 포함하고 디하이드록시 화합물 성분단위에 에틸렌글리콜 단위를 포함하는 폴리에스테르 수지 변성폴리프로필렌 수지를 폴리에스테르에 대하여 0.5 내지 2중량%로 첨가 블렌딩시켜 예비중공성형품을 제조하고, 예비중공성형품의 구부를 가열 결정화시키고, 연신블로우 성형 및 몸체부위틀 열고정시켜 제조한 것이며 내습성이 강해 장기간 보관사용시에도 경시내열성 저하가 없는 효과가 있다.The present invention provides a heat-resistant polyester container with improved durability, a polyester resin modified polypropylene resin comprising a terephthalic acid unit in the dicarboxylic acid component unit and an ethylene glycol unit in the dihydroxy compound component unit with respect to the polyester It is manufactured by adding and blending at 0.5 to 2% by weight to prepare a pre-molded product, heat crystallization of the bent part of the pre-molded product, and stretching the blow-blow molded body and heat-setting the body part. There is no effect.
