Conclusions:
Differential scannic calorimetry was used to determine melting point of 4,4'-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with 3-aminopropyldiethylamine and 2-piperazin-1-ylethylamine. There was no freezing point evident for the sample on cooling. A glass transition (Tg) was evident on heating. A melting point was not evident. The average onset of the Tg is 260.3°K (-13.0°C).
