Abstract
An improved method is provided for processing of rubbers in which one of the rubbers is a synthetic green strength polymer, the improvement being the addition of the synthetic green strength polymer at the second stage of mixing rather than at the prior art first stage. The method can be used for preparing rubber compounds whenever a synthetic green strength polymer is used as one component of the rubber compound.
