摘　要：概述了热塑性弹性体的挤出加工条件和挤出螺杆的设计要求，并通过分析比较指出，对于某一类热塑性弹性体的挤出加工来说，即便其组成材料相同而只是组分比例有差异，也很难从整体上给出统一的加工条件和螺杆设计的特定规则。

Abstract：The processing conditions and screw design for extrusion of thermoplastic elastomers are described. It is found from the analysis that the different processing conditions and screw designs should be set for the different thermoplastic elastomers, even though they are composed of the same materials at different blending ratio.
