  • Polymerization of ethylenically unsaturated monomers employing alpha-halo substituted diacyl peroxides
    Patent number: 4071677
    Abstract: Asymmetrical organic diacyl peroxide polymerization initiators having enhanced initiator efficiency and characterized by the presence of an acyclic acyl group of four or more carbon atoms having bromo or halo substitution at the alpha carbon atom, the other acyl group being different and heterosubstituted. However, when the alpha-halosubstituted acyl group is branched chain the other acyl group may be hydrocarbon.
