Aerylonitrfle and acrylamide copolyner has been synthesized by radical polymerization using ammonium persuLfate and sodium bisulfite as initiator. The dependences of pervaporation characteristics on the copolymer composition, feed concentration and operating temperature have been studied. In order to improve the separation properties of the copolymeric membranes, the blend membranes of poly(aerylonitrfle-co-aerylamide)(Ⅰ) and poly(aerylonitrile-co-acrylie acid)(Ⅱ) have been made from their DMF solutions. It was found that the separation factor of the blend membrane had a much greater value when the weight fraction of copolymer(Ⅱ) was less than 50%.
