The preparation of silicon dioxide (SiO 2 )@poly(acrylic acid) (PAA) microsphere was reported. The modified microspheres can be well dispersed in polyvinyl chloride (PVC) matrix. The structure of SiO 2 @PAA microspheres can be well‐controlled and its mixtures with chlorinated polyethylene (CPE) for controlling diisooctyl terephthalate (DOTP) migration from PVC matrix. The results showed that the migration of DOTP was decreased with increasing content of SiO 2 @PAA microspheres, and the use of CPE together with SiO 2 @PAA microspheres has a synergistic effect on the reduction of DOTP migration. Moreover, CPE can enhance the interface combination between SiO 2 @PAA microsphere and PVC, and good dispersibility was observed in PVC/CPE/SiO 2 @PAA composites.
