NATURAL RUBBER, RUBBER COMPOSITION USING THE SAME, AND TIRE

摘要

The invention provides a natural rubber that is obtained from a natural rubber latex to which a preservative has been added and/or that is obtained by adding a preservative to the coagulation product of a natural rubber latex and setting the resulting water-containing coagulation product aside to dry for a predetermined time. A natural rubber having stable dynamic properties is obtained by preventing a reduction in molecular weight even when the natural rubber coagulation product is set aside (aged) while having a high water content. An isothiazoline compound is an example of the preservative that is used. The invention further provides a rubber composition containing the natural rubber and a tire that is produced using this rubber composition.
