✦ Synopsis

The poly ( acrylonitrile-co-vinylidene chloride-co-divinylbenzene ) beads with macroporous morphology were synthesized by suspension polymerization. The use of dichloroethane as a solvating diluent resulted in copolymer beads having highly porous structures. These have been reacted with hydroxylamine in methanol, which generates amidoxime groups. The precursory resins were readily functionalized within 0.5-1 h. A detailed analysis is made of the pore structure of resins in the anhydrous state including pore size distribution and specific surface area.

Weak acid ion-exchange membranes were obtained on the basis of PVC/poly(MMA-co-DVB) interpolymer-type systems. Carboxylic groups were introduced by acid hydrolysis of ester groups in poly(MMA-co-DVB) copolymer. It was found that suitable conditions for preparation of carboxylic membranes were: tempe
