SOLUTION COMPOUNDING PROCESS FOR ACHIEVING UNIFORM FINE PARTICLE SIZE DISPERSION OF CURING AGENTS

摘要

Rubber curing agents such as quinoids are solution compounded to achieve a uniform or homogeneous distribution thereof in a rubber composition. The curing agents are initially solubilized in an organic polar solvent and then mixed with the rubber masterbatch solution. The solvent is then removed. A uniform fine distribution of the curing agent results in improved physical properties. The present invention is particularly suitable as a sealant composition for tires.
