- Conclusions:
- 4,4’-Isopropylidenediphenyl, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with cyclohex-1,2-ylenediamine does not display a freezing point on cooling. It does have a glass transition with an average onset 272.7°K (-0.5°C). The DSC results indicate the sample is amorphous
and not crystalline in nature. - Executive summary:
4,4’-Isopropylidenediphenyl, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with cyclohex-1,2-ylenediamine does not display a freezing point on cooling. It does have a glass transition with an average onset 272.7°K (-0.5°C). The DSC results indicate the sample is amorphous
and not crystalline in nature.
Reference
Diaminocyclohexane-Epon 828 adduct does not display a freezing point on cooling. It does have a glass
transition with an average onset 272.7°K (-0.5°C). The DSC results indicate the sample is amorphous
and not crystalline in nature.
Description of key information
