Abstract

Dicumyl Peroxide (DCP) and 2,5-Dimethyl-2,5-di(tert-butylperoxyl) hexane (Trigonox 101) were used to modify a Bismaleimide (BMI) thermoset. Differential Scanning Calorimetry (DSC) analysis on samples containing up to 4 wt% of DCP showed that with increasing amount of DCP added, more chemical reaction occurred at the lower temperature range. The addition of both catalysts significantly increased the glass transition temperature as determined by Dynamic Mechanical Analysis (DMA), mainly due to higher degree of crosslink reaction of BMIs within the network. Thermal Gravimetric Analysis (TGA) showed that thermal stability of the network was not significant influenced by the addition of catalyst. Overall thermal properties of BMI thermosets were enhanced by catalysts addition.
