<P>PROBLEM TO BE SOLVED: To provide a phenol resin composition improved in compatibility to rubber, particularly to nonpolar rubber, and to provide a rubber composition improved in reinforcement effect by using the phenol resin composition for precision molding application for electric/electronic components and the like and use for a tire and the like. Ž<P>SOLUTION: The resin composition for rubber compounding contains an etherified phenol resin. Preferably, in the etherified phenol resin, hydrogen of a phenolic hydroxy group is substituted by an alkyl group, a phenyl group, and/or an allyl group, and an etherification rate of the hydroxy group is 20-80%. The resin composition for rubber compounding further contains hexamethylene tetramine or hexamethoxy-methylated melamine resin as a curing accelerator. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
