PROBLEM TO BE SOLVED: To provide an easy, low-cost manufacturing method, whereby coloration of a polybutadiene rubber caused by a conventional manufacturing method is prevented by adding water at a manufacturing step. SOLUTION: The method for manufacturing a diene rubber includes: adding a polymerization terminator after polymerization of a monomer used, thereby terminating the polymerization; and subsequently adding an antioxidant thereto. The diene rubber obtained by the manufacturing method shows suppressed coloring. COPYRIGHT: (C)2011,JPO&INPIT
