研究三元乙丙橡胶（EPDM）/聚丙烯（PP）/聚烯烃弹性体（POE）热塑性弹性体的性能。结果表明：随着溴化辛基酚醛硫化树脂SP-1055用量增大， EPDM/PP/POE的硫化程度增大，硬度呈上升趋势，拉断伸长率、拉断永久变形和压缩永久变形呈减小趋势，定伸应力和拉伸强度先提高后降低；使用POE810，EPDM/PP/POE热塑性弹性体的100%定伸应力、拉伸强度和拉断永久变形较大，压缩永久变形较低，综合物理性能较好。

The properties of EPDM/PP/POE thermoplastic elastomer were investigated in this study. Firstly,the addition level of brominated octyl phenolic curing resin SP-1055 was studied. It was found that with the increase of addition level of SP-1055, the cross-link degree of EPDM/PP/POE increased, the hardness also increased, while the elongation at break, permanent tensile set and compression set all decreased. Secondly, the experimental test results showed that by using POE810, the EPDM/PP/POE possessed good overall physical properties, such as large tensile modulus at 100%elongation, tensile strength and permanent tensile set, and low compression set.
