Abstract : The major objective of the contract was the development of reverse osmosis membranes with the capability of converting seawater to potable usage. The work was divided into 4 programs as follows: (A) A membrane barrier layer formed by the interfacial poly-condensation of polyethylenimine and isophthaloyl chloride. (B) A membrane barrier layer formed by the interfacial poly-condensation of poly(epichlorohydrin-secondary diamines) and diacid chlorides. (C). An asymmetric polyimide membrane. (D) Optimization of porous substrates for composite membranes. jg p.5
