ABSTRACT:
A novel and safe ethylenically unsaturated peroxyester composition derived from an ethylenically unsaturated dicarboxylic acid is provided, as well as processes for making and using the composition. The peroxyester composition comprises about 0.04 to about 0.70 mole fraction of a first component compound having a formula I: ##STR1## about 0.32 to about 0.50 mole fraction of a second component compound having a formula II: ##STR2## about 0.04 to about 0.70 mole fraction of a third component compound having a formula III: ##STR3## wherein Q is an unsaturated ethylene divalent radical and R.sup.1 and R.sup.2 are organic substituents. Polymeric-peroxides are prepared via polymerizing the peroxyester compositions. The peroxyester compositions are also used for curing unsaturated polyester resins and for initiating polymerization of ethylenically unsaturated monomers.
