Abstract: The result of the analysis on the kinetics of cross-linking and scission of polymers subjected to irradiation states that the cross-linking is not directly proportional to the dose, especially in the early stage of irradiation.So a rapid drop of molecular weight should be observed at the small dose.This is demonstrated by the result of [η] of irradiated polymethylene terephthalates.

Key words: Polyesters, Radiation effect, Cross-linking and scission
