Abstract

Elastomeric bladders having improved resistance to spontaneous rupture when inflated are made by vulcanizing a homogeneous mixture of synthetic polyisoprene having 90% to 98% cis-1,4 linkages, finely divided silicon dioxide or carbon black, and vulcanizing agent while simultaneously forming the mixture into hollow tubular bodies. After being formed the bodies are solvent extracted to remove unreacted vulcanizing agent and the degradation products of the vulcanizing agent. Following the solvent extraction a nontoxic, nonleachable antioxidant is imbibed into the bodies by contacting the bodies with a liquid solution of the antioxidant.
