Abstract

Graft copolymerization of styrene diluted with various solvents and aqueous mineral acids solutions onto electron beam irradiated poly(ethylene-co- tetrafluoroethylene) (ETFE) films was investigated. The swelling behaviour of the obtained polystyrene grafted ETFE films and their pristine counterpart towards pure solvents and monomer/solvent mixtures was evaluated together with the solubility parameters of grafting mixtures components. The kinetics of styrene grafting under the same dilution conditions was also studied. Styrene non-solvents such as methanol and ethanol were found to enhance the degree of grafting to great extent compared otherwise good solvents such as toluene. Grafting was also further enhanced by addition of acids. The synergetic effects of dilution of styrene with methanol or ethanol and acid addition observed in this study provide means to reduce key grafting parameters: monomer consumption and irradiation dose in a way possibly leading to improvements in economic and the mechanical properties of the graft copolymer membranes.
