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.

Tread enhancement additives for tires

The disclosure relates to a composition for use in a number of applications including tires. The composition comprises a blend of a rubber component, reinforcing particulate fillers, and based on 100 parts by weight (phr) of the rubber component; from about 5 phr to about 70 phr of a terpene phenol resin having a softening point temperature in the range of from about 100&#xb0; C. to about 170&#xb0; C. and having a hydroxyl value in the range from about 5 to about 30. In one embodiment, the terpene phenol resin has a number average molecular weight of from about 700 Da to about 790 Da, a weight average molecular weight of from about 930 Da to about 1090 Da, and a polydispersity index of from about 1.25 to about 1.45.
