Nylon compositions are prepared by anionic polymerization of at least 75% of a lactam with up to about 25% of an epoxy component in the presence of a basic catalyst and a promoter that can be used in lactam polymerization wherein, in a preferred embodiment, the epoxy component is a modified epoxy resin containing physical property enhancing constituents. The nylon compositions are prepared by mixing a fraction of a lactam with the epoxy component and the promoter to form liquid mixture A, mixing remaining lactam with the catalyst to form liquid mixture B, mixing liquid mixtures A, A and B in the ratio ranging from 1/1 to 4/1 to form liquid mixture C, injecting liquid mixture C into a mould maintained at a temperature of about 100 to 200°C wherein a chemical reaction takes place whereby the liquid is converted to a solidified mass in less than about 2 minutes, and removing the nylon composition in the form of a molded object.
尼龙组合物的制备方法是:在碱性催化剂和可用于内酰胺聚合的促进剂存在下,将至少 75% 的内酰胺与最多约 25% 的环氧组分进行阴离子聚合,其中,在一个优选的实施方案中,环氧组分是含有物理性能增强成分的改性环氧树脂。尼龙组合物的制备方法是:将一部分内酰胺与环氧组分和促进剂混合形成液体混合物 A,将剩余的内酰胺与催化剂混合形成液体混合物 B,将液体混合物 A、A 和 B 按 1/1 至 4/1 的比例混合形成液体混合物 C,将液体混合物 C 注入温度保持在约 100 至 200°C 的模具中,在模具中发生化学反应,使液体在不到约 2 分钟的时间内转化为固化物,然后取出模塑物形式的尼龙组合物。
