摘　　要：采用共混的方法制备了改性聚氯乙烯超滤膜．主要是分别将经低温等离子体改性的聚氯乙烯和二聚异丁烯－马来酸酐共聚物与聚氯乙烯共混，采用适当的制备工艺。PVC is blended with PVC powder treated by O 2 plasma.Carboxyl group are formed in the molecular chains. The optimal treatment conditions are:input power 40 W,treatment time 2 mins, prepressure 1.33 Pa, and operating pressure 26.66 Pa. The water flux of the ultrafiltration membrane prepared by the blending of them is 960 L·m -2 ·h -1 , and its rejection M W is 45 000. The membrane of the blend of PVC and alternating copolymer of diisobutylene maleic anhydride can also easily attain the above mentioned specifications.
