摘　　要：由于邻苯二甲酸二丙烯酯(DPA)能与双马来酰亚胺(BMI)/二烯丙基双酚A(DABPA)树脂能发生交联反应,因而当使用DPA作为活性稀释剂,改善BMI/DABPA树脂体系的加工性能,降低树脂体系粘度时,能兼顾树脂的耐热性能.通过实验测定DPA在树脂中的不同比例,树脂的粘度及其固化后的热失重数据,分析确定DPA的适宜含量为(wt%)15%-20%之间.Since cross-linking reaction occurred in the mixture of diallyl phthalate（DPA） and BMI/DABPA resin systems, low molecular weight volatiles will not be retained in the resin system with DPA as the diluent to improve the mechanical properties. DPA will reduce the viscosity of the resin system, but do not affect the heat resistance. The paper analyzes the relation between the data of viscosity and TGA curves with different wt% in resin system and the appropriate proportion of DPA in the system will be 15 % -20 %.
