The curing behavior and properties of bismaleimide (BMI), bisoxazoline (1,3‐PBO), and oleic acid ternary copolymers are investigated. It is found that the cure temperature of BMI/1,3‐PBO or BMI/1,3‐PBO/oleic acid could be lowered, compared with that of BMI. The reason lies in the copolymerization reaction between BMI, 1,3‐PBO, and oleic acid. SEM results confirm that 1,3‐PBO and oleic acid could toughen BMI system because of the formation of ester–amide bonds and the long fat chain of oleic acid. The cured resins from BMI/1,3‐PBO or BMI/1,3‐PBO/oleic acid have superior heat resistance and water resistance. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci 2008
