摘要：研究了凯芙拉纤维与尼龙 6单体通过阴离子原位聚合制备热塑性复合材料的方法。以氢氧化钠为引发剂 ,甲苯二异氰酸酯 (TDI)为活化剂 ,确定体系的聚合温度为 160℃ ,引发剂、活化剂用量为6.42 m ol/L ,聚合时间 60 min,在此条件下聚合速度较快 ,单体转化率 1h后达 95 %以上。研究发现 ,凯芙拉纤维经酰化处理后 。
An thermoplastic composites of Kevlar fiber/nylon6 was prepared via anionic in situ polymerization. The process parameters of the in situ polymerization system with NaOH as an initiator and tolylene diisocyanate (TDI) as an activator were selected as: the polymerization temperature of 160℃, the concentration of the initiator and the activator of 6 42 mol/L, and polymerization time of 60 min. The polymerization speed was increased to such an extent that monomer conversion reached above 95% in 1 h under these conditions. It was found that Kevlar fiber subjected to acylation wouldn't inhibit the caprolactam anionic polymerization.
