Progress in understanding of deformation mechanism of polyolefin elastomers during tensile stretching

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.
