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

Embodiments relate to a method of producing a modified double metal cyanide complex, a method of producing a monol or polyol that includes providing the modified double metal cyanide complex, an alkylene oxide polymerization process that includes providing the modified double metal cyanide complex, a batch, semi-batch, or continuous manufacturing process that includes providing the modified double metal cyanide complex, and a polyether polyol prepared using the batch, semi-batch, or continuous manufacturing process that includes providing the modified double metal cyanide complex.

Polyether polymerization process

The invention relates to oligomerization of olefins, such as ethylene, to higher olefins, such as a mixture of 1-hexene and 1-octene, using a catalyst system that comprises a) a source of chromium b) one or more activators and c) a phosphacycle-containing ligating compound. Additionally, the invention relates to a phosphacycle-containing ligating compound and a process for making said compound.
