Wy. Chiang et Fc. Ding, Copolymerization of N-(4-carboxyphenyl)-maleimide with acrylonitrile and the properties of its membrane, J POLYM R, 7(4), 2000, pp. 251-255
N-(4-Carboxyphenyl)maleimide (N-4-CPMI, M-1) was copolymerized with acrylon
itrile (AN, Mt) to prepare the copolymer. The monomer reactivity ratios and
Alfrey-Price Q, e values were determined as r(1) = 0.56, r(2) = 0.84, Q(1)
= 2.0, Q(2) = 0.6 and e(1) = 2.06, e(2) = 1.2. The membrane of copolymer c
ontaining 0.25% CPMI had a good tensile property (67.3 MPa). The 0.75 mole%
membrane had an excellent selectivity factor (alpha = 45.3).
