Abstract

Cellular materials are produced by mixing a polymerizable material or a rubber composition with a blowing agent such as benzoyl peroxide, a a 1 azo-di-isobutyronitrile or azo-cyclohexanoic dinitrile, and exposing the mixture to high energy radiation for a time that is sufficient to cause decomposition of the blowing agent to the required extent and to cause polymerization of the material or composition to proceed to the solid state. The Specification refers to the treatment of natural and synthetic rubbers and of a paste of styrene and silica.ALSO:Cellular materials are produced by mixing a polymerizable material or a rubber composition with a blowing agent such as benzoyl peroxide, a a 1 azo-di-isobutyronitrile or azo-cyclohexanoic dinitrile, and exposing the mixture to high energy radiation for a time that is sufficient to cause decomposition of the blowing agent to the required extent and to cause polymerization of the material or composition to proceed to the solid state.
