Abstract Thermoplastic elastomers (TPEs) are attractive materials because they combine the processing advantages and recycling potential of thermoplastics with the flexibility, low modulus, and soft touch of elastomers. In this article, the synthesis, characterization and mechanical properties of polyolefin TPEs are reported. A facile procedure is employed, through the chain-walking polymerization, to fabricate random copolymers of 1-octene with 1-decene and cyclopentene. The effect of the type and the feedstock comonomers concentration on the microstructure, the total branching and the branch-type distribution is studied. A comprehensive investigation on the mechanical behavior by uniaxial stretching until failure, step-cycle and creep tensile tests is carried out. All the copolymers behave as elastomers, with different mechanical properties strongly depending on the composition, structure and crystallinity.

1-辛烯与 1-癸烯和环戊烯共聚的聚烯烃热塑性弹性体

摘要 热塑性弹性体 (TPE) 是一种极具吸引力的材料，因为它们结合了热塑性塑料的加工优势和回收潜力，以及弹性体的柔韧性、低模量和柔软触感。本文报道了聚烯烃 TPE 的合成、表征和机械性能。采用一种简便的方法，通过链行走聚合，制备 1-辛烯与 1-癸烯和环戊烯的无规共聚物。研究了类型和原料共聚单体浓度对微观结构、总支化和支化类型分布的影响。对通过单轴拉伸直至失效、步进循环和蠕变拉伸试验的机械行为进行了全面研究。所有的共聚物都表现为弹性体，
