摘要

对已经商品化的Perkin-Elmer TMS-2型热机分析仪进行改进

用来测量聚合物材料的热释蠕变行为。按照TSCr分步加载的程序

用弯曲法测量了-83〜30℃温度范围内低密度聚乙烯的玻璃化转变松弛过程

并从TSCr谱上计算其相应的分子参数

实验结果与用扭转的 TSCr方法所得结果相等

因此这是一种研究聚合物材料松弛行为的方便可行的技术。

Abstract

A commercial available Perkin-Elmer tnermome-chanical ana— lyzer TMS-2 was modified in our laboratory in order to measure the Thermally Stimulated Creep(TSCr)behavior of polymer materials. The glass transition relaxation of low density polyethylene in the temperature range between -83 to + 30 ℃ was resoluted by means of the fractional loading TSCr procedure in bending loading manner

and the molecular parameters were calculated from the TSCr spectra. The results were in good agreement with that obtained from the torsional loading TSCr experiment. Therefore this is a convenient technique to study the relaxation behavior of polyιner materials.
