The present invention is directed to a copolymer of 1,3-butadiene or isoprene and a monomer of formula I or formula II where R 1 is a covalent bond or C1 to C8 linear or branched alkanediyl; R 2 , R 3 , R 4 are independently C1 to C8 linear or branched alkyl or -OR 6 , where R 6 is C1 to C8 linear or branched alkyl, with the proviso that at least one of R 2 , R 3 , and R 4 is -OR 6 , and where R 5 is hydrogen or C1 to C8 linear or branched alkyl. The invention is further directed to a rubber composition including the copolymer, and a pneumatic tire containing the rubber composition. The invention is further directed to a method of making such a copolymer.
