Irradiation Effects on Styrenedivynilbenzene Copolymer(In Chinese)

The hydrophobie support styrenedivynilbenzene copolymer(SDB)and hydrophobic catalyst(Pt-SDB)have been irradiated by ~(60)Coγ-rays under air or D_2 atmosphere.A series of analyses such as SEM,DSC,TG and FTIR have been used to discuss the radiation effects.The results indicated that no obvious effects of irradiation on the morphology of the external surface,the heat proper- ties and chemical structure,but has little effect on hydrogen isotopic exchange.
