<p>PROBLEM TO BE SOLVED: To provide a production method of an epoxidized natural rubber that is inexpensive and has good productivity, an epoxidized natural rubber obtained by the production method, a rubber composition for a tire containing the epoxidized natural rubber, and a pneumatic tire manufactured by using the epoxidized natural rubber.SOLUTION: The production method of an epoxidized natural rubber is carried out by using a nonionic surfactant having a cloud point of 68°C or lower. In the production method, the nonionic surfactant is preferably added by 0.1 to 3 pts.mass with respect to 100 pts.mass of a rubber component in a natural rubber latex.</p> |
