Embodiments are directed towards the use of a supported biphenylphenol polymerization catalyst made from a biphenylphenol polymerization precatalyst of Formula I via a gas-phase or slurry-phase polymerization process under gas-phase or slurry-phase polymerization conditions to make a polymer.

Biphenylphenol polymerization catalysts

A process to form a crosslinked composition, said process comprising thermally treating a composition that comprises the following components: a) an olefin/silane interpolymer, b) a cure catalyst, and c) a multi-vinyl compound. A composition comprising the following components: a) an olefin/silane interpolymer, b) a cure catalyst, and c) a multi-vinyl compound.

Crosslinked compositions from olefin/silane interpolymers

A polyolefin-polydiorganosiloxane block copolymer may be prepared by Piers-Rubinsztajn reaction.

Polyolefin-polydiorganosiloxane block copolymer and method for the synthesis thereof

A method of polymerizing an olefin monomer to make a polyolefin composition comprising a polyolefin polymer, the method comprising contacting a solution of an alkane-soluble non-metallocene precatalyst dissolved in an alkane solvent with an activator so as to make a trim catalyst comprising an alkane-soluble non-metallocene catalyst, feeding the trim catalyst, as a solution in an alkane solvent or supported on a support material as a dry powder or a slurry thereof in an alkane solvent, into a polymerization reactor, and polymerizing the olefin monomer with the trim catalyst in the polymerization reactor, thereby making the polyolefin composition.
