The maximum (apparent) viscosity does not appear at the highest acrylic acid dosage but at a molar ratio of polyacrylic acid to anhydroglucose units of ca.
The weight loss was observed because the inhibitor 2-MBT undergoes oxidative degradation which starts to degrade above 200[degrees]C; in addition, polyacrylic acid and poly (pyrrole) start to degrade above 300[degrees]C.
It is noteworthy that all the three curves displayed a more or less similar pattern of weight loss indicating that MWCNT had no influence on the crosslinking and the subsequent maturation of polyacrylic acid matrix.
