Patent ID: 8765859

Claim:
A method for making a vulcanized elastomeric composition, comprising: (a) mixing together (i) an elastomer containing unsaturated carbon-carbon bonds in its molecular structure; (ii) a compound having the formula B-A-S x —N, wherein B is an azaheterocyclic oxygen or sulfur containing moiety, or an allyltin moiety; S x comprises a polysulfide, wherein x is 2 to about 10; A is a linking atom or group that forms a bridge between B and S x ; and N is a blocking group; (iii) a filler comprising a surface group that binds to the B moiety of the compound, wherein the filler is carbon black or a mixture of carbon black and a mineral filler; and (iv) a cure agent; and (b) curing the composition; wherein the azaheterocyclic oxygen or sulfur containing moiety is selected from the group consisting of formulas I-III: wherein X is oxygen or sulfur; wherein each of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 is independently hydrogen, a branched or linear C 1 -C 20 alkyl group, a branched or linear C 3 -C 20 cycloalkyl group, a branched or linear C 6 -C 20 aryl group, a branched or linear C 7 -C 20 alkylaryl group, or A.
