Abstract
Stable peroxyesters containing both conjugated diene and peroxidic groups in their molecule; e.g., t-butylperoxysorbate, t-hexylperoxysorbate, 1,1,3,3-tetra-methylbutylperoxysorbate, are copolymerizable with other polymerizable monomers and the said compounds are useful for polymerizing monomers as free radical initiators.
