Functionalized elastomer containing a boron group
The present invention is directed to a copolymer of a first monomer and a second monomer, wherein the first monomer is selected from the group consisting of 1,3-butadiene, isoprene, and styrene; and the second monomer is of formula I or V ##STR00001##
wherein R.sup.1 is a covalent bond, phenylene, a linear or branched alkane diyl group containing 1 to 10 carbon atoms, or a combination of one or more phenylene groups and one or more linear or branched alkane diyl groups containing 1 to 10 carbon atoms; R.sup.2 and R.sup.3 are independently linear or branched alkyl groups containing 1 to 10 carbon atoms; R.sup.4 is hydrogen or a linear or branched alkyl group containing 1 to 10 carbon atoms; and R.sup.5 is a linear or branched alkane diyl group containing 1 to 20 carbon atoms, or a bridging aromatic group. 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.
