- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:

- 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).
- Executive summary:
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).
