Abstract
A polyamide macromonomer (1) having a vinylbenzyl group at one chain end was copolymerized with 2-vinylpyridine (VP) using a radical catalyst in N,N-dimethylformamide at 60°C. The resulting graft copolymer composed of a poly(VP) stock and polyamide branches was separated from the unreacted 1 by fractional precipitation in dimethyl sulfoxide-water mixed solvent. A graft copolymer membrane was easily prepared by casting a methanol solution of the copolymer, while a homopolyrner of VP had poor film-forming ability. The crosslinked membrane was found to exhibit extremely high permeability of cupric chloride in aqueous solution.
