Abstract:

A novel low temperature curing  resin was prepared by the 1,3-dipolar cycloaddition polymerization of N,N,N′,N′-tetrapropargyl-p,p′-diamino diphenyl methane(TPDDM) and 1,1′-bezidomethyl-4,4′-biphenyl(BAMBP) at 70 ℃. The variation of TPDDM with BAMBP of the reactively functional groups during the polymerization was traced by FTIR, the polymerizing reaction of TPDDM with BAMBP and the reaction kinetics were investigated  using FTIR and differential scanning calorimetry(DSC) at a variety of heating rates. The kinetic parameters at different temperatures including the reaction order, activation energy and pre-exponential factor were obtained. The apparent  reaction order n,  activation energy Ea and  pre-exponential factor A calculated from FTIR and DSC data were mutually evidential.
