摘要：
The present invention provides a modified natural rubber having a reduced tan δ, a method for producing the modified natural rubber, a rubber composition produced using the modified natural rubber, and a pneumatic tire produced using the rubber composition. The present invention also provides a modified natural rubber having a reduced tan δ, a method for producing the modified natural rubber, a rubber composition produced using the modified natural rubber and achieving good fuel economy and abrasion resistance at the same time, and a pneumatic tire produced using the rubber composition. The present invention relates to a modified natural rubber having a phosphorus content of 200 ppm or less and a total content of sodium and potassium of 350 ppm or less. The invention also relates to a modified natural rubber having a phosphorus content of 200 ppm or less and a nitrogen content of 0.2% by mass or less.
