The present invention relates to a monomer composition for synthesizing recycled plastic, a method for manufacturing same, and a recycled plastic, a molded article, and a plasticizer composition using same, wherein, while recovering terephthalic acid from (co)polymers synthesized from monomers comprising terephthalic acid, the content of isophthalic acid, which is an impurity, is greatly reduced, and terephthalic acid with an increased particle diameter can be guaranteed. La présente invention concerne une composition de monomère pour la synthèse de plastique recyclé, un procédé de production de celui-ci, et un plastique recyclé, un article moulé, et une composition de plastifiant l'utilisant ; dans ledit procédé, tout en récupérant l'acide téréphtalique à partir de (co)polymères synthétisés à partir de monomères contenant de l'acide téréphtalique, la teneur en acide isophtalique, qui est une impureté, est fortement réduite, et l'obtention d'acide téréphtalique ayant un diamètre de particule accru peut être garantie. 본 발명은 테레프탈산을 포함한 단량체로부터 합성된 (공)중합체로부터 회수하면서도 불순물인 이소프탈산의 함유량을 극히 감소시키고, 입자 직경이 증가된 테레프탈산 확보가 가능한 재활용 플라스틱 합성용 단량체 조성물, 이의 제조방법, 그리고 이를 이용한 재활용 플라스틱, 성형품 및 가소제 조성물에 관한 것이다.
