| 中文摘要: |
| 研究了聚烯烃热塑性弹性体POE(Engage 8180)的静态力学性能和动态力学性能，探讨了炭黑用量和炭黑表面预处理对POE性能的影响。结果表明：交联和填充都将使POE的结晶度减小；硅烷偶联剂VTPS(乙烯基三叔丁基过氧化硅烷)和A151(乙烯基三乙氧基硅烷)能够有效增强炭黑与POE间的界面作用，从而使胶料各项物理性能得到改善，特别是内部动态温升大幅度下降，接近SBR的水平。这种胶料具有优异的耐老化性能、较高的动态模量和回弹性以及优异的耐磨性能。 |
| 英文摘要: |
| The static and dynamic properties of crosslinkable thermoplastic poly olefin elastomer(TPOE) Engage 8180 were studied and the influence of the loading level and surface pretreatment of carbon black on the properties of TPOE was investigated.The results showed that the crystallinity was declined by crosslinking and filling；the interfacial effect between carbon black and TPOE was effectively increased by silane coupling agent，vinyltri-tert-butyl-peroxy-silane(VTPS) or inyltriacetoxy silane(A-151)，thus the physical properties of compound improved，especially the internal heat build-up decreased significantly closing to the level of SBR.Engage 8180 possessed excellent aging property，higher dynamic modulus and superior wear resistance. |
