Abstract
본 발명은 폴리에스타 필름을 제조할 때 발생하는 산업폐기물인 폴리에틸렌테레프탈레이트 올리고머(이하 폐 PET라 칭함)를 이용한 불포화 에스테르 수지(이하 PET 불포화 폴리에스테르라 칭함) 및 그 제조방법에 관한 것으로, PET 올리고머를 원료로 이용하는 불포화 폴리에스테르 수지의 제조에 있어서, 다가알코올과 PET 올리고머를 금속 아세테이트 촉매하에서 반응시키는 1단 반응 및, 이 1단 반응에서 얻은 PET 올리고머에 다가포화산, 다가불포화산과 반응시키는 2단 반응으로 생성된 것을 특징으로 하는 불포화 폴리에스테르 수지의 제조방법.The present invention relates to an unsaturated ester resin (hereinafter referred to as PET unsaturated polyester) using a polyethylene terephthalate oligomer (hereinafter referred to as waste PET), which is an industrial waste generated when producing a polyester film, and a method of manufacturing the same. In the production of unsaturated polyester resin using an oligomer as a raw material, a one-stage reaction in which a polyhydric alcohol and a PET oligomer are reacted under a metal acetate catalyst, and two in which the PET oligomer obtained in this one-stage reaction is reacted with a polysaturated acid and a polyunsaturated acid. Method for producing an unsaturated polyester resin, characterized in that produced by the reaction.
