Studies on salts of amine-containing polymers with benzoic acids. III. PolyCtyN-dimethylaminoethyl methacrylate-g-polyethylene with benzoic acids

Abstract:

PolyWW-dimethylaminoethyl methacrylate) [poly(DMAEMA)] was grafted onto a commercial polyethylene film by means of y-irradiation, and the grafted films were reacted with various liquid-crystal-forming benzoic acids. When polymeric salts consisting only of poly(DMAEMA) and the benzoic acids were heated, dissociation of salts was observed, but with poly(DMAEMA) grafted onto polyethylene films, salt dissociation or crystallization of dissociated acids could be avoided, and interesting morphologies, including liquid-crystal phases, were observed for the svstems of benzoic acids-poly(DMAEMA-ff-polvethvlene). © 2000 John Wiley & Sons, Inc.
