摘　　要：比较了自制的丙烯酸丁酯-苯乙烯-丙烯腈核壳共聚物(ASA)、抗冲型ACR和CPE对PVC塑化性能和冲击强度的影响,采用SEM观察了试样冲击断面的微观形貌。结果表明:①ASA对PVC塑化性能和冲击强度的改性效果优于CPE,次于ACR;②SEM照片表明,3种冲击改性剂增韧效果的排序为ACR>ASA>CPE。Influences of self-made butyl acrylate-styrene-acrylonitrile（ASA） core-shell copolymer,impact ACR and CPE on the plasticizing and impact properties of PVC were studied.The morphologies of ruptured surfaces of samples were observed by SEM.The results indicated that：（1） the modification effects of ASA on the plasticizing and impact properties of PVC were better than those of CPE and less than those of ACR;（2） SEM results showed that the toughening effects of the three kinds of impact modifier were in order of ACRASACPE.
