## Abstract Monodisperse poly (chloromethylstyreneβcoβdivinylbenzene) particles were firstly prepared by a twoβstep swelling method. Based on this media, one kind of weak cation ion exchange packings was prepared. It was demonstrated that the prepared packings have comparative advantages for biopol

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
