Abstract:
A novel class of lanthanide metal salen complexes can be used as an ingredient of a catalyst system. The catalyst system can be used in polymerizations of ethylenically unsaturated hydrocarbon monomers.
Abstract:
A process for preparing a polydiene, the process comprising the step of polymerizing conjugated diene monomer with a lanthanide-based catalyst system in the presence of a vinylsilane, an allylsilane, or an allylvinylsilane.
Abstract:
A catalyst composition that is the combination or reaction product of ingredients including an iron-containing compound, a hydrogen phosphite, and an aluminoxane can be used in the polymerization of conjugated diene monomers.
Abstract:
A method for preparing a functionalized polymer, the method comprising the steps of polymerizing monomer to form a reactive polymer, and reacting the reactive polymer with a polycyano compound.
Abstract:
A method for preparing a functionalized polymer, the method comprising the steps of (i) polymerizing monomer with a coordination catalyst to form a reactive polymer; and (ii) reacting the reactive polymer with a nitrile compound containing a protected amino group.
