Title:
OXIDATION RESISTANT NATURAL RUBBER AND A METHOD FOR ITS PRODUCTION
Document Type and Number:
WIPO Patent Application WO/2016/040665
Kind Code:
A8
Abstract:
A method for stabilizing a natural rubber such as guayule. The method includes the step of introducing at least one of an amine and a phenolic anti-oxidant, such as MADA, to a latex form of the rubber under conditions such that the anti-oxidant becomes chemically bound to the rubber. The method includes the further step of subsequently treating the rubber to remove at least a substantial portion of entrained resins. The method can yield a rubber composition of, for example, guayule rubber and including an anti-oxidant chemically bound thereto. The resultant rubber can be suitable for use in tire construction.
