摘要：

The curing behavior of bisphenol A diglycidyl ether (BADGE) has been studied by differential scanning calorimetry and IR spectroscopy using active esters, the trifunctional compound 1,3,5-triacetoxybenzene (TAB) and tetrafunctional tetraphenoxycarbonyl pentaerythritol (TPCP) as curing agents, with which no free hydroxyl groups are left in the cured resins. The effects of the ratio of ester groups to epoxide groups (r) in the reaction mixture on the glass transition temperature (T(g)) and the thermal stability of the cured resins were also examined by thermomechanical analysis and thermogravimetry respectively. The T(g) has the maximum value of 72-degrees-C at r = 1 for either TAB or TPCP as curing agent. The thermal stability increases with increasing value of r.
