Ultraviolet(UV)-induced graft polymerization of acrylamide(AAm)on polypropylene substrates was successfully conducted using dibenzyl trithiocarbonate(DBTTC)as photoinitiator.It was confirmed by chemical analysis and surface morphology observation with attenuated total reflectance Fourier transform infrared spectroscopy,X-ray photoelectron spectroscopy,and scanning electron microscopy.A possible mechanism for this graft process was presented,which suggested that,under UV irradiation,the C=S bond in DBTTC could split and abstract a hydrogen from the polypropylene surface and a surface free radical was then formed,and initiated the graft polymerization of AAm.
