摘　　要：采用熔融接枝制备SEBS-g-MAH,分析了不同反应条件对接枝率及其接枝效率的影响。通过FTIR确定SEBS的接枝产物的产生;用酸碱滴定法、FTIR确定MAH的接枝率;DSC、TG研究SEBS及其接枝产物SEBS-g-MAH的热性能。SEBS- grafted - MAH prepared by melt - grafted method was studied and the effects of different conditions on graft ratio and graft efficiency were analyzed. The SEBS - grafted - product was confirmed by FTIR. The graft ratio of MAH was determined by acid - base titration and FTIR and the graft ratio working curve of SEBS - g - MAH was given too. The thermal property of SEBS - g - MAH was studied by DSC and TG.
