A new modifier for bismaleimide (BMI), 2,4,6‐tris(2‐allylphenoxy)‐1,3,5‐triazine (TAPT), with higher yield was prepared by a phase‐transfer catalyzing (PTC) procedure through the reaction of cyanuric chloride with 2‐allylphenol in the presence of aq. NaOH using tetrabutyl ammonium bromide in chloroform. The thermo‐homopolymerization behavior of TAPT was investigated by differential scanning calorimetry (DSC), and the results showed that TAPT does not polymerize on heating. The copolymerization reaction of TAPT and 4,4'–(bismaleimidophenyl) methane (BMDPM) was also studied. and the results showed that TAPT can effectively improve mechanical properties of BMDPM. The better results were obtained when the TAPT composition was in the range 30–40 wt %. The glass fabric reinforced TAPT/BMDPM matrix composite with excellent mechanical and electric properties could be prepared by processing the resin (30 wt % TAPT) in dimethylformamide (DMF)/toluene (1:1, v/v) solution. © 2001 John Wiley & Sons, Inc.
