Title

EFFECT OF TRIPHENYLPHOSPHINE ON THE CURE REACTION AND THERMAL STABILITY OF DIGLYCIDYL ETHER OF BISPHENOL A-BASED EPOXY RESIN

Pages

  875-885

Abstract

 Asulphone-nitrogen containing heterocyclic ring, tetraphenylthiophene diamine (TPTDA) was prepared and used as curing agent together with triphenylphosphine (PPh3) to cure diglycidyl ether of a bisphenol A-based EPOXY RESIN (DGEBA). Activation energies (Ea) for curing DGEBA/TPTDA and DGEBA/ TPTDA/PPh3 systems by using DSC data and Kissinger equation are 66.6 kJ/mol and 76.6 kJ/mol, respectively. The increase in Ea can be due to polymerization of DGEBA by PPh3 and formation of larger molecules with reduced mobility before curing with TPTDA to start. Ea of THERMAL DEGRADATION of cured DGEBA/TPTDA and DGEBA/TPTDA/PPh3 systems by using TGA data and Horowitz-Metzger equation are 56.0 kJ/mol and 128.0 kJ/mol, respectively. The onset decomposition temperature and the char yield have increased from 230oC to 320oC and from 21.4% to 32.5% for the above systems, respectively. The addition of PPh3 to the curing mixture enhanced char formation and improved THERMAL STABILITY of the resin.
