Two-stage grafting onto polyethylene fiber by radiation-induced graft polymerization and atom transfer radical polymerization



Two-stage graft polymerization onto polyethylene (PE) fiber was demonstrated. The graft side chain was formed by radiation-induced graft polymerization. A PE fiber was irradiated with an electron beam and immersed in a vinyl monomer solution. The terminal of the formed graft chain was halogenated using N-bromosuccinimide. The halogenated graft chain was then extended by atom transfer radical polymerization to obtain block-copolymer grafted PE fibers. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
