dc.description.abstractTo improve water wettability of polyurethane (PU) ,graft copolymerization with acrylic acid (AA) and crotonic acid (CA) was performed using benzoyl peroxide (BO) initiator. The grafting reaction was carried out by placing the membranes in aqueous solutions of AA and CA at constant temperatures. Variations of graft yield with time ,temperature, initiator and monomer concentrations were investigated.The optimum temperature, polymerization time, monomer and initiator concentrations for AA were found to be 70 C; 3h; 1.5 M; 5.0 x 10-2 M and for CA 70 C; 1h; 1.5 M; 4.0 x 10(-2) M , respectively. The grafting membranes were characterized by FTIR spectroscopy and scanning electron microscopy (SEM) analysis and the effect of grafting on equilibrium water content (EWC) of PU membranes was obtained by swelling measurements.tr_TR
