【摘要】 在实验室用悬浮法制备了一种新型的含苯环的系列低聚物添加剂 Ｐ Ｓ－ Ｌ，研究了添加量为８ ％ （ 质量分数） 时共混体系的纺丝情况，同时考察了共混纤维卷绕丝的聚集态结构对其牵伸性能的影响。实验表明，添加剂 Ｐ Ｓ－ Ｌ 的加入使纤维的可拉伸性能有所改善，并能够明显的改善共混纤维的力学性能，共混纤维的强度、初始模量增大，断裂伸长降低，回弹性变好，纤维刚性也有所改善；同时，共混纤维的染色性能也有很大的提高。更多还原

【Abstract】 A new low polymer additive PS-L was synthesized by suspension polymerization. The spinnability, mechanical performance and dyeability of PP/PS-L (8% by m) blends were studied. The results showed that the additive PS-L improved the drawability, rebound elasticity, dyeability and rigidity of PP fiber, and the fiber’s strength, initial modulus were increased but its elongation was reduced.更多还原
