  • Alpha halo substituted asymmetrical diacyl peroxides in co-initiator systems
    Patent number: 4107419
    Abstract: Organic peroxide polymerization co-initiator compositions and their use in the initiation of the polymerization of certain monomers and comonomers such as vinyl chloride, ethylene and methyl methacrylate. The co-initiator composition contains an alpha halo substituted diacyl peroxide and a coperoxide selected from t-alkyl peresters of t-hydroperoxides, peroxydicarbonates, acyl peroxycarbonic esters, and aliphatic diacyl peroxides. Typical is acetyl 2-chlorooctanoyl peroxide with t-butyl peroxy neodecanoate.
    Type: Grant
    Filed: March 4, 1977
    Date of Patent: August 15, 1978
    Assignee: Argus Chemical Corporation
