Phosphorus containing epoxy for flame retardant II: curing reaction of bis-(3-glycidyloxy) phenylphosphine oxide

[[abstract]]©1996 Wiley - The curing reaction of a phosphorus containing epoxide, bis-(3-glycidyloxy) phenylphosphine oxide (BGPPO), was studied by differential scanning calorimeter (DSC) using dynamic and isothermal methods. Kinetic parameters and activation energy of the BGPPO cured with diamine or dianhydride curing agents were determined. The dynamic activation energies were significantly larger than the isothermal ones. Via isothermal analysis technique, the activation energies of BGPPO cured with 4,4 prime -diaminodiphenylmethane, dicyanodiamide, methyl tetrahydrogen phthalic anhydride, and phthalic anhydride were found to be 69.5, 83.5, 93.6, and 90.6 kJ/mol, respectively. These values were comparable with those of other commercial epoxy curing system.[[fileno]]2020117010060[[department]]化學工程學
