Any other information on results incl. tables

Using a Mettler-Toledo Model DSC12E Differential Scanning Calorimeter, CP-163,625-BV was shown to soften from 46 to 195°C as indicated by a very broad endotherm, and then to decompose at temperatures above 200°C as shown by a sharp exotherm. Decomposition was immediately followed by an endotherm, indicating melting of decomposition products.

Applicant's summary and conclusion

Conclusions:
CP-163,625-BV was found to decompose above 200°C before melting.
Executive summary:

CP-163,625-BV decomposes before melting above 200°C, melting point can't be determined.
