Abstract
Abstract Organic peroxides having two peroxide functional groups and containing in the molecule an amino nitrogen atom, having the general formula : wherein : R 1 , R 2 are each an alkyl radical having 1 to 8 carbon atoms, optionally aryl substituted, preferably a tertiary alkyl group such as t.butyl, t.amyl, t.octyl and cumyl; R 3 is hydrogen, an alkyl radical having 1 to 8 carbon atoms, a cycloalkyl radical having 5-6 carbon atoms in the ring, an aryl radical, or an arylalkyl radical, optionally halogen, alkoxy, carboalkoxy or alkyl mono or poly substituted; R 4 is a methylene, ethylene or trimethylene radical, optionally halogen, alkoxy, carboalkoxy, aryl or alkyl mono or poly substituted; and R s is a methylene or ethylene radical, optionally halogen, alkoxy, carboalkoxy, aryl or alkyl mono or poly substituted. The peroxides are employed in the cross-linking of plastomers, natural and synthetic elastomers and thermosetting resins.
