본 개시내용은 공정을 제공한다. 본 공정은 (i) 7.0 g/10분 이상의 용융 유량(MFR I2)을 갖는 소비 후 재순환 폴리프로필렌(PCR-PP: post-consumer recycled polypropylene)을 제공하는 단계; 4,4'-옥시디벤젠설포닐 아자이드(DPO-BSA)를 PCR-PP에 첨가하는 단계; (iii) PCR-PP를 DPO-BSA와 용융 배합하는 단계; (iv) 5 g/10분 이하의 용융 유량(MFR I2)을 갖는, DPO-BSA가 커플링된 PCR-PP(DPO-BSA coupled PCR-PP)를 형성하는 단계를 포함한다. The present disclosure provides a process. The process includes (i) providing a post-consumer recycled polypropylene (PCR-PP) having a melt flow rate (MFR I2) equal to, or greater than, 7.0 g/10 min; (ii) adding a 4,4′-oxydibenzenesulfonyl azide (DPO-BSA) to the PCR-PP; (iii) melt blending the PCR-PP with the DPO-BSA; and (iv) forming a DPO-BSA coupled PCR-PP having a melt flow rate (MFR I2) equal to, or less than, 5 g/10 min.
