A process for the production of an oligomer oil by the polymerization of a feedstock containing one or more C to C 1-olefins in the presence of a solid unsupported metallocene- and activator-containing catalyst system which is formed by removing the solvent from a solution of the soluble metallocene- and activator-containing catalyst system.

Oligomerization using a solid, unsupported metallocene catalyst system

The present invention relates to novel compositions useful in coating, adhesive, structural, film, sheet, pipe, toys, house siding, asphalt, thermoplastic, elastomer and other applications. The novel compositions comprise copolymers of at least one vinyl and/or vinylidene monomer and at least one high reactivity polyolefin. The copolymers are produced by polymerizing at least one high reactivity polyolefin and at least one vinyl monomer in the presence of a free radical initiator.

Copolymers of high vinylidene polyolefins with vinyl or vinylidene monomers produced by free radical polymerization

A multistep process for the selective production of an oligomer oil having predetermined properties in which the first step involves the polymerization of a feedstock containing one or more C to C 1-olefins in the presence of a catalyst comprising a bulky ligand transition metal catalyst and in which a subsequent step involves the olgiomerization of at least a preselected fraction of the product of the first step.
