Abstract: This paper investigated the influences of BRand DCP on PS/LLDPE/SBSb lend.Addition of BRwas found to decrease the impact strength of PS/LLDPE/SBSb lend. When DCPwas added together,it is found that the co-crosslinking of BRand PEtook place,which resulted in the improvement of the blend's ductility.At the same time,the decomposition of Pskinhibit666ue to the presence of BR. The roles of BRand DCPin PS/LLDPE/SBSblends were also studied by using SEM,DSCand selective extraction techniques.
