Abstract

The techniques of isothermal and dynamic thermogravimetry have been used to study the degradation of six nitrated homodisperse fractions of poly( N-vinylcarbazole). The effects of nitrogen content and molecular weight of the samples on kinetic parameters are reported. Increasing the heating rate or using higher isothermal temperatures causes a sudden mass-loss and an increasing sample temperature was observed. An induction period in which −NO 2 scission took place may be the cause of this sudden mass-loss.
