  • Heterocyclic peroxides
    Patent number: 3948891
    Abstract: Heterocyclic nitrogen-containing peroxides are prepared by reacting a tertiary alkyl hydroperoxide with a nitrogen heterocycle substituted cycloalkene such as 1-(4-morpholinyl)cyclohexene. The products are useful initiators of vinyl polymerization where a peroxide initiator of relatively high thermal stability is desirable.
    Type: Grant
    Filed: October 4, 1974
    Date of Patent: April 6, 1976
    Assignee: The Dow Chemical Company

  • Method for preparing polyperoxydicarbonate esters
    Patent number: 3935243
    Abstract: Dialkyl alkylenebis(peroxydicarbonates) and oxyalkylenebis(peroxydicarbonates) and corresponding higher polyfunctional peroxydicarbonic acid esters are useful initiators of vinyl polymerization. These compounds are prepared by reacting a sodium alkylperoxycarbonate with a diol bis(chloroformate) at from about -10.degree.C to about 20.degree.C.
