摘　　要：考察胶粉(WTRP)POE-g-(MAH-co-St)/POE共混型热塑性弹性体的性能和结构以及再加工性。实验结果表明:活化胶粉/POE-g-(MAH-co-St)/POE的比例为70/15/15时,该热塑性弹性体的拉伸强度可以达到9.71 MPa,断裂伸长率达到463.71%,且具有再加工性,可以循环利用。添加POE-g-(MAH-co-St)之后的共混料,界面结合更加紧密,提高了共混料的力学性能。The structure, property and reprocessability of the thermoplastic elastomer of WTRP/ POE-g-（ M AH-co-St）/ POE composites were studied. The results indicated that the tensile strength of the thermoplastic elastomer of WTRP/ POE-g-MAH/POE（75/15/15） could be reach 9.71 MPa,elongation at break reached 463.71% ,and the composites had reprocess ability. Good interfacial bonding was formed in the composites that had POE-g-（MAH-co-St）. This led to its good mechanical properties compared with the corresponding composites without it.
