Little has been reported about the action of benzoyl peroxide as a vulcanizing agent for silicone rubber. Knowledge of this action seems to be of consider- able importance, since benzoyl peroxide is the most widely used vulcanizing agent at the present time. Apparently no studies of the kinetics of peroxide decomposition in silicones have been undertaken. It is not known quantitatively whether or not the silicones influence the decomposition rate in the way some of the solvents studied by Cass and by Nozaki and Bartlett do. In this paper we report the results of work undertaken to determine the number of cross-links introduced into polydimethylsiloxane by benzoyl peroxide during the normal vulcanizing process. The apparent efficiency of cross-link production has been determined as a function of the concentration of peroxide, the method of vulcanization, and of the filler content of the sample.
