【摘要】 借助过氧化物引发剂和双马来酰亚胺助交联剂合成了部分硫化型三元乙丙胶EPDM。研究了部分硫化型EPDM和聚丙烯PP热塑性共混物的形态和性能。显微摄影揭示了适当配比的共混物为一种半互穿网络结构。DSC、物理力学性能试验等的研究表明,半互穿网络结构的试样具有优异的物理力学性能和二次加工性能。更多还原

【Abstract】 The partial vulcanized EPDM has been prepared by means of peroxide initiator and bismaleimide co-cfosslinking agent. The morphology and propertie-s of thermoplastic blends consisted of partial vulcanized EPDM and polypropylene have been studied. Photomicrograph revealed that the blend with appropriate proportion is a semi-interpenetrating network(semi -IPN) strusture.The studies by DSC,mechanical properties test etc. indicate that the specimens with semi-IPN structure possess excellenst mechanical properties and reprocessing character.更多还原
