摘要

以乙烯为单一原料采用串级催化体系制备了乙烯/1-己烯无规共聚物

具有从60℃到120℃宽的熔融峰

其储能模量在100 MPa 以下

研究此热塑性弹性体的形状记忆性质。采用DSC、DMA 等手段定量表征

结果表明

选择恰当的变形温度

共聚物的形状固定率和形状恢复率可达90%

实现较好的形状记忆性能。

Abstract

Thermoplastic polyolefin elastomers which are soft and easy processing have potential usage for non-structural applications. The thermal

mechanical and shape memory properties of this thermoplastic elastomers were investigated with differential scanning calorimetric (DSC) and dynamic mechanic analysis (DMA). The results showed that was important for the better shape memory with both of the shape fixity rate and shape recovery rate up to 90% can be reached by choosing a proper deforming temperature in a broad range of melting temperature.
