Ronald J Hoxmeier: Selective hydrogenation process. Shell Oil Company, November 7, 1989: US04879349 (45 worldwide citation)

A method for selectively hydrogenating a polymer containing monomer units from at least two different conjugated diolefins, one of which conjugated diolefins is more substituted at the 2, 3 and/or 4 carbon atoms than is the other. The selective hydrogenation can be accomplished with selective hydrog ...
