摘要：

The copolymers of maleic acid with acrylonitrile can be applied in the fabrication of membranes for ultrafiltration, pervaporation and enzyme-immobilization. In this paper we present new results on the synthesis of maleic anhydride-acrylonitrile copolymer by radical copolymerization in organic solvents. We have examined the effect of the synthesis conditions: solvent, monomer ratio, and monomer concentration on the composition and molar mass of the copolymer. The composition of copolymers was determined by different methods: elemental analysis, conductometric titration in water/organic media, titration in nonaqueous medium, FTIR and H-1 NMR spectra. The data were compared and the most reliable and convenient method was identified.
