Abstract
A process for the preparation of a (co)polymerizable composition containing a diol bis(allyl carbonate) monomer and an aromatic diacyl peroxide comprising dissolving in said monomer a powdered peroxide composition in which the peroxide is mixed with an organic desensitizing agent, e.g. dicyclohexyl phthalate, which has a melting or softening point higher than 40.degree. C. and forms 20-80% by weight of said peroxide composition. The process permits, with the aid of simple stirring equipment, to obtain good quality (co)polymerizable compositions at room temperature without vigorous stirring and in a relatively short time. Also disclosed is the (co)polymerization of the (co)polymerizable compositions thus prepared.
