摘　　要：PAE为活性高分子树脂,固含量越高稳定性越难控制。本文探讨一种固含量为35%PAE的制备工艺条件及与市售增强剂进行比较。实验证明选择胺酸摩尔比为1.05:1,聚酰胺预聚体催化剂的最佳用量为1.0%(对总量的摩尔比),反应温度为170℃左右,环氧氯丙烷与聚酰胺预聚体摩尔比为1.1:1,反应温度为60℃。环氧化反应后得到黏度为200～240mPa·s(涂-4杯50～60s)的聚酰胺树脂,干抗张强度优于市售PAE,湿抗张强度略低,PAE/CMC或PAE/CMS二元增强系统比单独使用PAE效果较优。PAE as an active polymer resin, the higher the solid content, the more difficult to control the stability of it. This paper discussed a solid content of 35% PAE of the preparation process conditions and with the commercially available strengthening agent for comparison. Results showed that the option of acid molar ratio was 1.05：1, polyamide prepolymer catalyst optimum dosage was 1.0% （molar ratio of the total）, the reaction temperature was about 170 ℃, epichlorohydrin and the polyamide Prepolymer molar ratio was 1.1：1, the reaction temperature set at 60℃. Epoxidation obtained by the viscosity of 200-240mPa＇s （Tu 4 cups 50-60s） polyamide resin, dry tensile strength was superior to commercially available PAE, wet tensile strength was slightly lower, PAE / CMC, or PAE / CMS dual strengthening systems was better than PAE alone.
