Abstract
ABSTRACTA series of bismaleimide‐triazine (BT) resins with and without O, O′‐diallyl bisphenol A (DABPA) were produced by mixing 2, 2‐bis (4‐cyanatophenyl) propane (BADCy) and MCBMI (2,6‐bis(4‐(1‐(4‐(4‐(2,5‐dioxo‐2,5‐dihydro‐1H‐pyrrol‐1‐yl)phenoxy)‐3‐methylphenyl)‐3‐oxo‐1,3‐dihydroisobenzofuran‐1‐yl)‐2‐methylphenoxy)benzonitrile). The resins show just one glass‐transition temperature (T g) and enhanced flexural properties as well as superior fracture toughness compared with commercial BDM/BADCy system, in which BDM is (N,N′‐bismaleimido‐4,4′‐diphenylmethane). Introduction of DABPA can decrease the curing temperature of bismaleimide‐triazine (BT) resins but increase its impact strength. When the mole of DABPA reach up to 1.2, the impact strength was increased by 1.34 times in comparison with BDM/ BADCy system. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 136, 47420.
