Abstract

PURPOSE: To provide the titled rubber having low rolling frictional resistance, high wet-skid resistance, and excellent breakage characteristics, and containing specific amounts of vinyl bond and a bond between carbon and a metal selected from Si, Ge and Sn.
CONSTITUTION: The polymerization reaction of butadiene monomer is carried out in a hydrocarbon solvent (e.g. cyclohexane) using an organic Li compound (e.g. n- butyl Li) as a polymerization initiator and a Lewis base (e.g. tetrahydrofuran) as a micro-structure controlling agent. The amount of the Li compound is 0.1W 5mg atom of Li per 100g of the butadiene monomer, and that of the Lewis base is 1.0W1,000mol/1atom of Li. The reaction is terminated by adding at least one halide of Si, Ge or Sn (e.g. SnCl2) as a coupling agent to the reaction mixture. An antioxidant (e.g. 2,6-di-t-butyl-p-cresol) is added to the mixture, and the objective polymer is recovered.
USE: Vulcanized rubber can be utilized for a tire and various industrial applications.
