PURPOSE:To obtain the titled agent outstanding in metering characteristics, dispersibility in rubber, etc., by blending a rubber with metal oxide, metal hydroxide and/or metal carbonate, acrylic acid and organic solvent, carrying out a reaction followed by elimination of the organic solvent. CONSTITUTION:The objective agent can be obtained by blending (A) 1-70wt.% of natural rubber and/or synthetic rubber (e.g., polyisoprene rubber), (B) 0.1-80wt.% of at least one kind of oxide, hydroxide, and/or carbonate of metal selected from alkali(alkaline earth) metals and zinc-group metals, (C) 0.1-70wt.% of acrylic acid, (D) 1-90wt.% of an organic solvent soluble for the rubber (e.g., trichloroethylene) and (E) 0.1-50wt.% of a higher fatty acid (e.g., stearic acid, oleic acid), carrying out a reaction followed by elimination the organic solvent D.
