PARTIALLY HYDROGENATED PHENOLIC RESIN, RUBBER COMPOSITION AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a novel partially hydrogenated phenolic resin, a rubber composition comprising the resin and exhibiting excellent grip performance and abrasion resistance, and a pneumatic tire comprising the rubber composition.SOLUTION: A partially hydrogenated phenolic resin is prepared by selectively hydrogenating double bonds other than those on aromatic rings of a phenolic resin and has a hydrogenation ratio of the double bonds of from 30 to 100% and a hydroxyl value of from 30 to 500 mgKOH/g.
