Abstract
A process is described for producing a coupled polymer by anionically polymerizing monomers selected from the group consisting of a vinyl aromatic hydrocarbon, a conjugated diene or both with an organo alkali metal compound to produce living polymer arms which are then contacted with a fullerene which reacts with the living polymer arms to form a coupled polymer. The coupled polymer has a novel composition and novel characteristics.
