Abstract
A functionalized macromolecule includes a hydrogenated interpolymer portion, a non-hydrogenated polymer portion, and the radical of a functional coupling agent covalently bonded to and linking those portions. The functional group of the coupling agent exhibits interactivity with silica. The interpolymer can include vinyl aromatic mer and conjugated diene mer, with at least some of the latter, typically at least 50 mole percent, having been hydrogenated.
