摘要

The copolymerizaiton of iso- or terephthaloyl chloride, m-phenylenediamine or diaminodiphenylsulfone, and 3,5-diaminobenzoic acid or 2,4-diaminobenzene sulfonic acid (or sulfonate) was studied. Copolymers with hgih reduced viscosity could be obtained by low temperature solution polymerizaiton, but not by interfacial polymerization. The reduced viscosity of the copolyamides obtained was dependent upon the species of the aromatic diamine compounds and the acid aceptors used. Low temperature solution copolymerizaiton with the comonomer 3,5-diaminobenzoic acid should be done without acid acceptors, because acid acceptors cause gelation. With 2,4-diamino-benzenesulfonic acid or 2,4-diaminobenzenesulfonate, pyridine or triethylamine as acid acceptors give polymers with higher reduced viscosity. The flat asymmetric membranes of the copolyamides prepared from terephthaloyl dichloride and mixed diamine components of 3,3'-diaminodiphenylsulfone and 3,5-diaminobenzoic acid showed not only god reverse osmosis performance, but also high chlorine resistance.
