Summary:An improved process for forming hydroperoxide derivatives of rubbery polymers. The hydroperoxide derivatives being particularly well suited for use as intermediates in forming graft rubbery polymers. The process involves dissolving a rubbery polymer in a monomer mixture and adding to the rubbery polymer/monomer mixture a photosensitizing agent. The rubbery polymer-monomer mixture is then oxygenated and exposed to light under conditions wherein triplet oxygen is converted to singlet oxygen. The improvement comprises adding to the rubbery polymer/monomer mixture a solvent capable of solubilizing the photosensitizing agent in the rubbery polymer/monomer mixutre. The solubilizer increases the yield of hydroperoxide derivatives of rubbery polymers formed by a factor of 3.
