摘要
聚烯烃弹性体是一种高性能聚烯烃产品,同时具备橡胶的高弹性、抗冲击性及普通塑料的易加工性,已经被广泛应用于黏合剂、混料、薄膜以及非织造布等领域.聚烯烃的微观结构与宏观行为之间存在着较为密切的联系,寻找结构-性能之间的关系能更好地为宏观行为提供理论依据.本文主要介绍了近10年聚烯烃弹性体拉伸形变机理的研究进展.
Polyolefin elastomer is a kind of polyolefin product with excellent performance. Based on its high elasticity properties and impact resistance as well as easy processing, the polyolefin elastomer is widely used in adhesive, mixture,films and nonwoven. The relationship between the microstructure and mechanical behavior in polyolefin is very close.Thus the investigation of "structure-property" relationship gives theoretical evidence in understanding the mechanical behavior. The research progress in understanding of the deformation mechanism during tensile tests for polyolefin elastomer during last ten years is discussed.
