| Abstract: | The glycidyl methacrylate(GMA)grafted SBS(SBS-g-GMA)was prepared by thermal initiated melt grafting in the presence of complex antioxidant(of the phenoltype),a phosphite and a flowability modifier(paraffin).The grafting rate of SBS-g-GMA copolymer was determined by titration measure,while the grafted SBS-g-GMA copolymer was characterized by FTIR.The effects of monomer content,DCP content,and time on the grafting rate were studied.The results showed that the grafting ratio increased with increasing DCP content and GMA content.SBS-g-GMA with higher grafting rate and better flowability was obtained. |
