Latest Patents

Doulgas J McLain holds a patent for a "Process for producing polymers with multimodal molecular weight." This invention provides a continuous process for catalytically polymerizing a monomer feed of ethylene and at least one comonomer. The process involves introducing a catalyst that includes a bulky ancillary ligand transition metal compound and monomer feed in an upstream reaction zone for polymerization. Further catalyst is introduced in a downstream reaction zone for additional polymerization, with the peak temperature in the downstream zone being at least 50 degrees Celsius higher than in the upstream zone and above 150 degrees Celsius. This innovative process economically produces polymers with good properties that are melt processable.
