Abstract : Common methods of compounding elastomers involves the addition of solid ingredients to the elastomer on a mill or mixing all ingredients together in a Banbury mixer. Such methods are not appropriate when the ingredients are sensitive to heat and when the polymer will not band on a mill. Another method common to the art of compounding polymers is to dissolve the polymer in a solvent and add the other ingredients to form a suspension. The suspension is then mixed with a liquid in which neither the polymer nor the compounding ingredients are soluble. The present method, according to the patent, provides a means for compounding polymers which have reliable composition and homogeneity in the overall formulation.
