Abstract

본 발명은 폴리에틸렌 테레프탈레이트와 폴리에틸렌 나프탈레이트와의 3종의 용융블렌드 조성물에 있어서, 상기한 폴리에틸렌 테레프탈레이트는 테레프탈산과 에틸렌글리콜과의 에스테르 반응에 의하여 합성한 것으로서 I.V=0.75 내지 0.85인 것이며, 상기한 폴리에틸렌 나프탈레이트는 디메틸-2,6-나프탈렌디카르복실레이트와 에틸렌글리콜과의 에스테르 교환반으에 의하여 합성한 것으로 I.V.=0.50 내지 0.60인 것을 특징으로 하는 폴리에틸렌 테레프탈레이트와 폴리에틸렌 나프탈레이트와의 3종 용융블렌드 조성물은 자외선 차단 효과가 우수한 포장 재료용 폴리에스터 수지이다.The present invention relates to three melt blend compositions of polyethylene terephthalate and polyethylene naphthalate, wherein the polyethylene terephthalate is synthesized by ester reaction of terephthalic acid and ethylene glycol, and is IV = 0.75 to 0.85. Polyethylene naphthalate is synthesized by transesterification of dimethyl-2,6-naphthalenedicarboxylate and ethylene glycol, and melts three kinds of polyethylene terephthalate and polyethylene naphthalate, characterized by IV = 0.50 to 0.60. The blend composition is a polyester resin for packaging materials that is excellent in the UV blocking effect.
