The thermal degradation rate constant of plastics containing polypropylene, polyethylene and polystyrene was analysed by using the distributed activation energy model. The values of activation energy E and frequency factor ko were widely distributed and differed between samples tested. The ko value was well correlated with E. It is extremely important to take the E distribution into consideration in estimating the weight of un-volatilized matter accumulated in the waste plastics degradation reactor.
