| 摘 要： | 通过阴离子淤浆聚合方法,以氢氧化钠为催化剂、异氰酸酯作活化剂,以惰性脂肪烃为分散剂,在不同的反应时间和140～150℃温度下,制得了不同相对分子质量的尼龙6,最高相对粘度17．5。通过熔融纺丝,获得了可纺性良好的纤维,其断裂强度5．0～6．9 cN／dtex。X衍射测试分析表明,同阴离子本体聚合尼龙6(MC尼龙6)和高粘度尼龙6比较,阴离子淤浆聚合尼龙6在二次成型中更易于生成轫性较好的γ晶型,具有更高的冲击强度。

| Abstract: | Nylon 6 with various relative molecular weight was prepared via anionic slurry polymerization with sodium hydroxide as a catalyst, aliphatic isocyanate as an activator and inert aliphatic hydrocarbon as a dispersant at 140 - 150℃and different reaction time. The maximum relative viscosity of the obtained nylon 6 can be up to 17. 5. The nylon 6 fiber can be produced with fairly good spinnability and breaking strength 5. 0 -6. 9 cN/dtex via melt spinning process. The nylon 6 prepared via anionic slurry polymerization was compared with nylon 6 prepared via anionic bulk polymerization (MC nylon 6) and high-viscosity nylon 6. The X-ray diffraction patterns showed that nylon 6 prepared via anionic slurry polymerization was prone to formingγcrystal with good tenacity during the secondary formation, hence it had higher impact strength. |
