Binary monomers of maleic acid and vinyl acetate are grafted onto poly(vinylidene fluoride) (PVDF)powder by pre-irradiation induced graft polymerization technique in emulsion solution.The co-grafting of binary monomers is successfully proved by FT-IR spectroscopy analysis.The influences of the absorbed dose,reaction temperature,reaction time,total concentration of monomers,and feed ratio of binary monomers on the degree of grafting are investigated.The thermal property of grafted PVDF powder was characterized by differential scanning calorimetry (DSC) and thermo-gravimetry analysis (TGA).
