摘要: Abstract Diffusion limitations have an impact on epoxy cure reactions near vitrification. The effects of diffusion control the rate reaction can be described by evolution a mobility factor, which is directly based experimental heat capacity measured with differential (scanning) temperature modulated calorimetry (D(S)TMC) as and factor coincide for resins studied. A model free volume theory Rabinowitch activated complex presented here. It relates apparent constant to difference between T g . Very good correlations are derived calculations normalized at 1/60 Hz. further extension allow factors different modulation frequencies also proposed. successfully predicts deceleration due limitations, demonstrates applicability D(S)TMC estimate effect reaction-induced vitrification polymerization overall kinetics.
