In order to study the kinetic mechanism of photochlorination of polyethylene, a proposed model was suggested in which the conversion of methylene (—CH2—) units to chloromethylene (—CHCl—) ones were considered as the main reaction. The simplified versions of the obtained kinetic model indicate that the reaction is first order with respect to the chlorine gas concentration and zero order with respect to the methylene groups concentration up to 40% of chlorination, where the concentration of γ-methylene sequences is high. The mechanism of reaction was exactly reversed at higher conversions.
