摘要： A rubber composition capable of giving a vulcanized rubber having improved rebound and elongation at break. The composition consists essentially of(1) 100 parts by weight of a rubber component composed of (a) 10 to 100% by weight of a modified conjugated diene polymer obtained by reacting a conjugated diene polymer having an alkali metal and/or an alkaline earth metal bonded thereto with a compound containing the ##STR1## bond in which M represents an oxygen or sulfur atom in the molecule, said modified conjugated diene polymer consisting essentially of 50 to 100% by weight of at least one C.sub.4 -C.sub.12 conjugated diene monomer and 0 to 50% by weight of an aromatic vinyl monomer, the amount of said compound bonded being at least 0.1 mole per mole of said polymer, and (b) 90 to 0% by weight of at least one rubber selected from the group consisting of styrene-butadiene copolymer rubber, styrene-isoprene copolymer rubber, polybutadiene rubber, polyisoprene rubber, butadiene-isoprene copolymer rubber, polyalkenamers and natural rubber, and(2) 0.01 to 1 part by weight of at least one amine selected from the group consisting of aliphatic primary amines and alicyclic primary amines.
