摘　　要：采用己内酰胺阴离子聚合合成MC尼龙,研究催化剂和活化剂的物质的量对MC尼龙聚合时间及结晶度的影响。结果表明,随着催化剂物质的量的增加,聚合时间缩短,结晶度呈现先增加后降低的趋势;随着活化剂物质的量的增加,聚合时间缩短,结晶度先增加,后略有降低。MC nylon was synthesized under the anionic polymerization of caprolactam to investigate the influence of the amount of catalyst and activator on the polymerization time and the crystalinity. The results show that with the increase of the amount of catalyst, the polymerization time shortens notably while the crystallinity increases at first and then decreases, that as the amount of cativator increases, the polymerization time shortens, and that the crystallinity increases at first and then decreases slightly.
