| 摘 要： | 本文根据聚丙烯（ＰＰ）与聚对苯二甲酸乙二醇酯（ＰＥＴ）共混对在熔 融状态下．流动粘度差阳溶度参数差大的特点，用挤出造粒的方法制得 共熔成纤目增强材料。通过扫描电镜观察．证实ＰＰ／ＰＥＴ比从９５／５到 ８０／２０时。ＰＥＴ均以纤维状结构分布在ＰＰ基质中。该共熔成纤体具有 良好的机械性能。在未加偶联剂时，拉伸强度虽略比纯ＰＰ低．但抗冲击 强度与纯ＰＰ相当。该结果可用于指导ＰＰ的改性和ＰＥＴ废料再生利用 工作。

| Abstract: | Based on quite difference of melt flow viscosity and solubility parameter of polypropylene (PP)and poly (ethylene terephthalate) (PET ), the self reinforced blends for PP/PET is made by extrusion, in which fiber morphology of PET is formed in the PP malrix when PP/PET is from 95/5 to 80/20. The fiber morphology of PET is ob- served under SEM and the diameter of the fiber is from 2 to 10μ Although the tensile strength of the materials slightly drow down the impact strength increase compared to that of pure PP. |
