The isothermal curves are shown in Figure 2.

From these data a Arrhenius curve is made in Figure 3. From the Arrhenius curve it appears that for MASC the Ln C is 35.1 and the activation energy (EA) is 155.8 kJ/mol.

Applicant's summary and conclusion

Conclusions:
MASC is stable below 200 °C. From the Arrhenius curve it appears that for MASC the Ln C is 35.1 and the activation energy (Ea) is 155.8 kJ/mol.
