Abstract
A method for producing a functionalized rubber that includes adding a diene rubber selected from natural rubber, a synthetic polyisoprene rubber or combinations thereof and an organic peroxide to a mixer, the organo peroxide may be represented by the formula R1—O—O—R2, wherein R1 is selected from hydrogen or an organic moiety of between 4 and 15 carbon atoms and R2 comprises a functional moiety. The mix composition may be mixed until the mix composition reaches a target temperature of between 120° C. and 190° C. and decomposing the organic peroxide to provide a decomposition product comprising the functional moiety and reacting at least a portion of the decomposition product with at least a portion of the diene rubber to produce the functionalized rubber.
