✦ Synopsis

Poly (m-phenylene isophthalamide), an aromatic polyamide is synthesized in the laboratory by low temperature solution polycondensation of m-phenylene diamine and isophthaloyl chloride. The polymer obtained by controlling the reaction parameters like mode of addition of isophthaloyl chloride, reaction temperature and time, is suitable for making a reverse osmosis membrane. The polymer is characterized by its physicochemical properties. Transport properties of the membrane are determined at 40 kg/cm2 operating pressure using 5000 ppm sodium chloride solution.
