摘要: 通过添加有机物或无机物对丙烯酸-丙烯酰胺共聚物进行共混改性,制备具有较好吸水性的丙烯酸-丙烯酰胺共聚纤维,分析和讨论了共混物对纤维形貌、热性能及吸水性能的影响。结果表明:纤维中添加亲水性聚合物聚乙烯醇后,玻璃化温度降低,纤维的柔韧性得到改善;纤维中添加海泡石后,其吸水速率和平衡吸水率均得到提高。

Abstract: Modified by blending with organic or inorganic substances,superabsorbent poly(acrylic acid-co-acrylamide) fibers were prepared.The effect of added components on the morphology,thermal properties and water?-absorptive capacity of the modified fibers were discussed in detail.The results show that the glass transition temperature of fibers blended with PVA was lowered and the fibers became more flexible,and that the absorptive speed and the equilibrium amount of water absorbency of sepiolite-filled fibers were increased obviously.
