Rubber compositions containing high purity lignin derivatives.

摘要

A tackifier composition for use in rubber compounds is disclosed. The tackifier comprises a pure lignin containing less than 50% by weight carbohydrate content. In another embodiment of the invention, the pure lignin functions as both a tackifier and an antioxidant. In yet another preferred embodiment of the invention, the improved tackifier produces synergistic results when blended with a commercial tackifier, and the antioxidant likewise yields synergistic results when mixed with a commercial antioxidant. <IMAGE>
