Abstract

PURPOSE:To obtain a rubber composition having improved cut-resistance and chipping resistance and suitable for treated of large-sized tire, etc., by compounding a rubber with a specific OH-containing cyclopentadiene polymer modified with one or more compounds selected from polybasic acid, etc. CONSTITUTION:100pts.wt. of a rubber is compounded with 1-30pts.wt. of a polymer produced by reacting (A) an OH-containing cyclopentadiene polymer produced by the thermal copolymerization reaction of (A1) 100pts.wt. of one or more compounds (e.g. cyclopentadiene) selected from the compound of formula (R is 1-3C alkyl; m is 0-6) having cyclopentadiene ring and its Diels-Alder addition product and (A2) 2-120pts.wt. of a compound having a polymerizable double bond and a hydroxyl group in one molecule (e.g. 3-22C unsaturated alcohols) with (B) one or more kinds of polybasic acids (anhydride or ester). The equivalent ratio of the carboxyl group and/or acid anhydride group and/or ester group of B to the hydroxyl group of A is 0.05-1.5.
