摘要: 反丁烯二酸酯类聚合物的气体分离性能研究已有许多报道。聚反丁烯二酸二叔丁酯(Po2=130barrer,ao2/N2=3.7)和聚反丁烯二酸二异丙酯(Po2=51barrer,ao2/N2=2.9)等都具有较好的氧氮分离性能。但是,由于这类聚合物的脆性很大,使其应用受到较大的限制。本文报道不同系列的反丁烯二酸酯类共聚物的合成和它们的氧氮透过性能。

Abstract: Several kinds of dialkyl fumarate copolymers were synthesized by radical copolymerization in the presence of AIBN. The permeabilities for oxygen and nitrogen of the copolymer membranes were determined. Effects of the copolymer composition on the gas permeability of the membrane were examined.
