| 摘 要： | 热重（ＴＧ）的结果表明，聚醋酸乙烯酯（ＰＶＡＣ）与聚丙烯（ＰＰ）共混后，其热稳定性增加。同时用Ｘ射线衍射及双折射等方法研究了ＰＶＡＣ／ＰＰ复合纤维的结构与力学性能的关系．发现拉伸倍数提高，纤维力学性能及ＰＰ结晶度增大，在体系中加入乙烯醋酸乙烯共聚物（ＥＶＡ），其相容性得到改善，力学性能进一步提高。

| Abstract: | The results of TG indicate that blending Polyvinyl acetate (PVAC ) and polypropylene (PP) can improve the thermostability of PVAC. This paper also studied the relation between structures and properties of PVAC/PP composite filaments by X-ray and double refraction. It can be found that the strength of fibers and crystallinity of PP creases with creasing strain rate. Adding EVA to PVAC/PP blends makes compatibility between PVAC and PP improved and the mechanical properties of filaments increase further. |
