摘要：

Poly-m-phenylene-iso(jt)-co-tere(100-.r)-phthalamide copolymers with different x values were synthesized and viscoelastic properties of the polymer solution were studied in the presence of lithium chloride nonsolvent additive in order to determine the size of the polymer aggregate in the solutionReverse osmosis membranes were also prepared using the polymers synthesized aboveThe membrane performance was then tested for the separation of sodium chloride solute and reference organic solutes, in order to obtain the average pore size and the pore size distribution of the membraneThe data for the pore size were further used to calculate the length of the polymer segment in the noncrystalline regionAn interesting correlation was found between the above length and the isophythaloyl content of the copolymer. © 1990, Gordon and Breach Science Publishers S.A.
