摘要： 高吸水树脂是一种应用比较广的功能性高分子材料.它的吸水率可高达几百倍乃至几千倍.但耐盐性较差.本文在丙烯酸钠外又增加了两种非离子性的单体丙烯酞胺和丙烯酸轻乙酷,旨在使所得到的高分子链上带有不同的亲水性基团,以提高吸水树脂的耐盐能力.文中还对影响树脂吸水率的主要因素进行了讨论.

Abstract: The permeability of five polyaryletherketone membranes to H2,CO2,O2,N2 and CH4 has been examined over a temperature range of 30～100℃. The dependence of the per-meability on the temperature and molecular structure of the polymer has been discussed.The PEK-A membrane exhibits both higher permeability and selectivity than PEK-C membrane,and the PEK-H membrane shwed the most gas selectivity among five polymer membranes studied.

Key words: polyaryletherketone, gas permeability membrane, structure-property relationship
