ABSTRACT:
This invention relates to the polymerization of vinylically-unsaturated monomers in the presence of a chain transfer catalysts where the polymerization process is initiated with hydrogen gas or a hydrogen atom donor rather than conventional free radical initiators. This invention further relates to an improved process for the polymerization of vinylically-unsaturated monomers in the presence of a chain transfer catalysts where the polymerization process is initiated with hydrogen gas.
