摘要

AbstractA variety of allylamine‐adducted bismaleimide (A‐BMI) resins were prepared by reacting bismaleimide (BMI), such as 4,4′‐bismaleimidodiphenylmethane (BDM) and 4,4′‐bismaleimidodiphenylether (BDE), with various molar ratio of allylamine through the Michael addition. The prepared A‐BMI resins are a partial crystalline or completely amorphous solid, depending on the amount of adducted allylamine. Two types of curing reactions for the A‐BMI resins were detected by differential scanning calormetry and verified by the mass spectroscopies of cured resins: one is the homopolymerization of A‐BMI resins through opening of the double bonds in the maleimide groups; the other is the reactions between allyl groups and benzene rings, taking place mainly when most of the double bonds in maleimide groups of the A‐BMI resins have been opened by allylamines. © 1993
