摘　　要：对比分析了采用丙酮与甲苯制备双酚A型双马来酰亚胺(BPA-BMI)的优缺点,确定选择丙酮法。采用了丙酮法制备双酚A型双马来酰亚胺,在丙酮中以顺丁烯二酸酐(MA)和2,2-双[4-(4-氨基苯氧基)苯基]丙烷(BAPP)为原料,醋酸酐为脱水剂反应得到高熔点的产物(BPA-BMI)。考察了MA和BAPP摩尔比、醋酸酐用量、无水乙醇用量和反应时间对双酚A型双马来酰亚胺产率的影响,并得到较好的反应条件为:n(MA)∶n(BAPP)=2∶1,醋酸酐用量为2 mL,65℃下反应8.5 h,BPABMI的产率达67.3%。The advantages and disadvantages of preparing bisphenol A bismaleimide(BPA-BMI)with acetone and toluene are compared and analyzed,and the acetone method is selected.Bisphenol A bismaleimide is prepared by acetone method.The maleic anhydride(MA)and 2,2-bis[4-(4-aminophenoxy)phenyl]propane(BAPP)are used as raw materials,and acetic anhydride is used as dehydrating agent to obtain high melting point product(BPA-BMI).The effects of the molar ratio of MA and BAPP,the amount of acetic anhydride,the amount of absolute ethanol and the reaction time on the yield of bisphenol A bismaleimide are investigated.The better reaction conditions are obtained as follows:n(MA)∶n(BAPP)=2∶1,the amount of acetic anhydride is 2 mL,the reaction time is 8.5 h at 65℃,and the yield of BPA-BMI can reach 67.3%.
