The present invention relates to a monomer composition for synthesizing recycled plastic, which extremely reduces the content of isophthalic acid, which is an impurity, while recovering from a (co)polymer synthesized from monomers including terephthalic acid, and can secure the terephthalic acid having an increased particle diameter, a manufacturing method thereof, and recycled plastic, molded articles and plasticizer composition using the same. 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.
