摘要:
Disclosed herein is a coupled polymer product comprising polymer with up to four polymer chains bonded to a functionalizing compound of formula II, wherein the polymer chains are comprised of conjugated diene-containing monomers optionally in combination with vinyl aromatic monomers and further include vinyl group-functionalized silane compound of formula I bonded within the polymer chain. Also disclosed are processes for producing the coupled polymer product as well as a rubber composition containing the coupled polymer product and tire components comprising the rubber composition.
