| Abstract: | Natural Rubber(NR) graft polyacrylates(EA/BA/AN/VAC) is prepared by using emulsion polymerization with KPS/SHS redox initiating system.The influences of factors such as reaction temperature、initiator amount、reaction time and monomers concentration on graft copolymerization were studied.The result showed that appropriate copolymerization condition is as following:reaction temperature is 60~70℃,intiator amount is 1.3 percent,and reaction time is 2.5 hours.IR spectrum proved that the copolymers of EA/BA/AN/VAC have been really grafted with NR. |
