| 摘 要： | 研究了在无活化剂存在时己内酰胺的碱性催化聚合反应。实验结果表明当聚合温度在190—220℃范围时制备的铸型尼龙其断裂伸长率在200％以上,最高达363％。并具有高耐冲击性能。与一般铸型尼龙相比较,该高延伸铸型尼龙具有较低的抗张强度、弹性模量、熔点、玻璃化转变温度、密度和结晶度。

| Abstract: | Caprolactam can be polymerized to a high elongation nylon-6 by alkaline catalyst, without ther use of activator. The polymerization can take place even when the temperature is lower than 220℃ or as low as 160℃. The effect of the polymerization temperature on the properties of the formed polymer has been investigated. The optimum condition of polymerization temperature is around 200℃. The polycaprolactam thus prepared has high impact strength and high elongation which is all over 200% and as high as 363%. Comparing with the conventional MC nylon-6, it has lower melting point, glass transition temperature, specific gravity and percent crystallinity. |
