✦ Synopsis

A series of bismaleimidertriazine (BT) resins were prepared from various dicyanate esters and 2,7-bis(4-maleimidophenoxy)naphthalene (BMPN), which contains a naphthalene group and an aryl ether linkage in the backbone. Their curing behaviors were characterized by differential scanning calorimetry. The exotherm temperature and polymerization reactivity were strongly affected by the chemical structure of the various dicyanate ester monomer. Thermal behaviors were investigated by thermogravimetric analyses and dynamic mechanical analyses. The glass transition temperatures ( T g ) of these cured resins with bismaleimide/dicyanate ester at the 1/2 molar ratio were in the range of 250-322ЊC, and exhibited excellent thermal stability up to 400ЊC in nitrogen. These results provided a structure-properties relationship for the cured bismaleimidertriazine resins.
