An equation, based on thermodynamic considerations to relate the glass transition temperature, T g , to compositional variation of a polymer system, is adapted in this article for modeling the T g vs. fractional conversion ( x) relationship of reactive thermosetting systems. Agreement between the ad

A single specimen of an epoxy/amine thermoset-glass fiber composite was examined, using a freely oscillating torsion pendulum operating at Ç 1 Hz, for different conversions (as measured by T g ) from T g 0 Å 0ЊC to T gϱ Å 184ЊC during cooling and heating temperature scans. T g was increased for succ
## Abstract The curing reaction of an epoxy resin [diglycidyl ether of bisphenol A (DGEBA)] combined with a methyl‐hexahydrophtalic anhydride (MHHPA) hardener and a benzyldimethylamine (BDMA) accelerator was studied over a temperature range of 60–140°C to build its isothermal time‐temperature‐trans
