| 摘 要： | 本文从的简化分子模型出发,改进了分子量和T_f间的关系式,得到了lnM=A-E/R·1/T_f的直线方程。对于分级的聚甲基丙烯酸甲酯的冷压和热压样品进行了不同荷重下温度-形变性貭的研究,所有的结果均符合上述方程式。本文并讨论了样品成型,施加荷重的大小等因素对聚合物温度-形变性貭的影响。

| Abstract: | Based on Kargin's simplified molecular model, a new linear relation between mole-cular weight and flow temperature is proposed, In M = AE/RTf.With fractionatedpolymethylmethacrylate as testing sample, both cold-molded and hot-molded, the experimental results are in accord with the above relation under different loading conditions. The effects of sample molding and loading weight on the temperature-deformation properties are discussed. |
