Popis:	Kinetics of consumption of benzoyl peroxide (temperature 92–115°) in triacetylcellulose in the presence of oxygen and kinetics of macromolecular rupture are desribed by first order equations. Effective rate constants of benzoyl peroxide consumption agree with corresponding constants of macromolecular degradation of triacetylcellulose and show a linear increase with the increase in the initial concentration of benzoyl peroxide at temperatures higher than 100°. A reaction system is proposed which involves monomolecular and chain breakdown of benzoyl peroxide and the breakdown and isomerization of peroxide macroradicals.
