Abstract
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 bel ieved 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 analysi s for the monomer and polymer were used for the elucidation of the the nnolysis mechanism. It has been concluded that pyrolysis of the polyme r occurs by depolymerization reaction followed by the pyrolysis of the monomer produced.
