Abstract
A composition comprising a tread enhancement additive for use in a number of applications including tires is disclosed. The tread enhancement additive is prepared from an unmodified alkyl phenol resin by reducing the hydroxyl value of the unmodified alkyl phenol resin, forming a modified alkyl phenol resin having a decreased hydroxyl value. The composition exhibits improved performance characteristics such as enhanced wet grip and decreased rolling resistance and improved abrasion resistance.
