Pyrolysis of N-acryloyl, N′cyanoacetohydrazide and its polymer

The rate of the gas-phase thermolysis of N-acryloyl, N′acetohydrazide has been measured in the gas phase in the range 482–517 K. This is believed to be a first order elimination reaction for which log A = 10.8 s⁻¹ and the activation energy E_n = 132 kJ mol⁻¹. Product analysis for the monomer and polymer were used for the elucidation of the thennolysis mechanism. It has been concluded that pyrolysis of the polymer occurs by depolymerization reaction followed by the pyrolysis of the monomer produced.
