| 摘 要： | 叙述了用凝胶渗透色谱（GPC）对多元共混方法制得的聚丙烯改性绝缘材料的相对分子质量及相对分子质量分布的表征研究，并就其对材料的加工应用性能的影响进行了初步探讨。实验结果表明：共混体系稳定，在加工过程中共混物不会产生胶联或降解。相对分子质量分布过宽，对材料高速挤出有不良影响。

| Abstract: | The characterization for the relative molecular mass and the relative molecular mass distribution of modified polypropylene blend was studied by gel permeation chromatography.The effect of relative molecular mass and its distribution on the processability of blend was examined. The results showed that the blending system was stable and the blend did not occur crosslinking and/or degradation. |
