Abstract
According to the proposed method for producing solid-porous synthetic rubber articles, a preselected portion of a molded blank of a raw V-like polymeric elastomer compound containing a blowing agent is subjected to ionizing radiation at a temperature below the decomposition temperature of the blowing agent, after which said blank is subjected to heat treatment at a temperature higher than, or equal to the decomposition temperature of the blowing agent. Despite its simplicity, the disclosed method provides for producing solid-porous rubber-like articles featuring high strength of their solid portion and excellent sealing qualities of their porous portion.
