AbstractThe kinetic equation for the pyrolysis gasification reaction of isotactic and atactic polypropylenes has been established. The difference in tacticity of the samples does not much affect the kinetic parameters. The exponentaof the intensity functionIF=Tδa(K·seca), concerning the severity of decomposition conditions, has been approximated as 0.039 (isotactic) and 0.040 (atactic), respectively from the kinetic parameters in this experiment. The calculated values of the product yield from Arrhenius equations,k= 2.0 × 1010exp(−40.9 × 103/RIF) (isotactic) andk= 1.2 × 1010exp(–41.4 × 103/RIF) (atactic), for theIFstandard agree with the experiment
