Beschreibung
Zusammenfassung:	The present invention provides a modified diene rubber which can be produced economically and improve low-loss properties and wear resistance of a rubber composition made therefrom, as compared with the conventional modified diene rubber. The present invention further provides: a method of producing the modified diene rubber; a rubber composition using the modified diene rubber; and a tire using the rubber composition. Specifically, the present invention provides: a modified diene rubber, produced by first oxidizing diene rubber latex and then adding a polar group-including hydrazide compound to a terminal end of a molecular chain of the diene rbber; a rubber composition, comprising the modified diene rubber; and a tire, comprising a tire member made of the rubber composition.
