Title: CATION EXCHANGE RESIN BY GRAFT POLYMERIZATION PROCESS
Abstract:
A process of preparing cation exchange resins by radiation grafting with copolymerization onto a perhalogenated fluorine-containing hydrocarbon polymer at least one functional monomer of formula CF2 = CF(CF2)nA or CF2 = CF-O(CFX-CFX)mA and at least one non-functional monomer of formula CF2 = CFY, and optionally in the presence of a polymerization inhibitor and a chain transfer agent wherein A is carboxyl, C1 to C6 alkoxycarbonyl, hydroxy-C1 to C6 alkoxycarbonyl, cyano, hydroxysulfonyl, fluorosulfonyl, or amide, one X is fluorine, the other X is selected from chlorine, fluorine and trifluoromethyl, n is an integer form 0 to 12, m is an integer from 1 to 3, and Y is a chlorine, fluorine, or a trifluoromethyl group.
