Effect of electron beam irradiation on the polypropylene/syndiotactic 1,2-polybutadiene blends:Radiation stabilization of polypropylene

摘要：

　　The effect of electron beam irradiation on polypropylene (PP),syndiotactic 1,2-polybutadiene (sPB) and their blends were studied.They were irradiated with the doses of 20 kGy,60 kGy,80 kGy and 100 kGy.Scanning electron microscopy and mechanical test were carried out to characterize the irradiated samples.When PP/sPB blends were irradiated,a part of PP macroradicals created by irradiation acts either as crosslinking agent making the PP and sPB crosslink or it is grafted onto sPB in the interface,which results in the interfacial adhesion stronger between PP and sPB compared with unirradiated PP/sPB blends.Significant improvement of mechanical properties has been obtained by the addition of sPB in the PP matrix when irradiated.The presence of sPB obviously decreases the PP sensitivity to radiation effects.
