Abstract
The present invention provides a modified natural rubber having a good balance of improved fuel economy, heat-aging resistance, processability, and breaking resistance, and a method for producing such a rubber. The present invention also provides a tire rubber composition and a pneumatic tire which are prepared using the modified natural rubber. The present invention relates to a highly purified, modified natural rubber whose pH is adjusted to 2 to 7.
