ABSTRACT:
This is an improvement upon a process which comprises anionically polymerizing monomers with an anionic polymerization initiator in a suitable solvent thereby creating a living polymer. The improvement comprises terminating the polymerization by the addition of hydrogen which reacts with the living polymer to terminate the polymer chain.
