4,4 - Methylenedi

Higher heat distortion temperatures are achieved using 4,4 -methylenedi-aniline (diaminodiphenyimethane) and diaminophenyl sulphone, in conjunction with an accelerator, but this is at some expense to chemical resistance. 

With an omme After determining the epoxy value and equivalent weight of the resin prepared according to b), a small sample is melted in the oven at 150 °C with the equivalent amount (0.25 mol per mol epoxy groups) of finely powdered 4,4 -methylenedi-aniline and the mixture well stirred for 30 s. After heating for 1 h at 150 °C, the sample is taken out it has now become insoluble and infusible.
