Applicant's summary and conclusion

Conclusions:
In conclusion, the melting
endothermic reaction to be
point of ucb 22060 was determined from the onset of the
107.7°c
Executive summary:

In order to determine the melting more precisely, further DSC-runs were recorded between

60”C and 180°C with a heating rate of 5 K/rein. During both main test runs the endothermic

heat effect was observed starting at 107.7”C. Details are given in Table 1. During the main

test runs, the samples lost OYO of their mass. After the measurements all samples were

colorless and melted. The temperature / time curve of the Ist main study is given in Figure 2.

In conclusion, the melting

endothermic reaction to be

point of ucb 22060 was determined from the onset of the

l07.7°c

which is equal to

380.9 K.
