Abstract

The decomposition of benzoyl peroxide in polystyrene in the presence of air has been studied spectrophotometrically over an expanded (55 to 98Β°C.) temperature range. Rates of decomposition of benzoyl peroxide in polyvinyl chloride films are also presented. Peroxide decomposition in both polymers obeys first‐order kinetics and the E~a~ for decomposition appears to change at or near the second‐order transition temperature of the polymers. Rates of peroxide decomposition are lower and energies of activation are higher in polyvinyl chloride than in polystyrene.

The rates of decomposition of benzoyl peroxide have been studied in water alone and in the presence of the components of graft copolymerization bath, viz. diphenyl and acrylic acid, in the temperature range of 363-403 K. Kinetic parameters such as reaction order for the peroxide, preexponential fact
