  • Composition with peroxides and process for avoiding scorching of ethylene polymer composition
    Patent number: 4025706
    Abstract: Vulcanizable ethylene polymer based compositions which are susceptible to scorching when processed at elevated temperatures, prior to vulcanization, in the presence of bis(tertiary-butyl peroxy isopropyl) benzene and/or 2,5-dimethyl-2,5-di(tertiary butyl peroxy) hexane, are protected against such scorching by the incorporation therein of cumene hydroperoxide and/or tertiary butyl hydroperoxide.
    Type: Grant
    Filed: January 23, 1976
    Date of Patent: May 24, 1977
    Assignee: Union Carbide Corporation
    Inventor: Donald Lincoln Schober
  • Composition with triallyl compounds and process for avoiding scorching of ethylene polymer composition
    Patent number: 4018852
    Abstract: Vulcanizable ethylene polymer based compositions which are susceptible to scorching when processed at elevated temperatures, prior to vulcanization, in the presence of certain organic peroxide compounds, are protected against such scorching by the incorporation therein of certain organic hydroperoxide compounds and organic compounds containing at least three allyl groups.
