Abstract: Techniques are provided for producing polymer particles of a size just slightly larger than the size of polymer fines. The technique may prevent or limit the occurrence of reactor fouls associated with large polymer particles. The technique also may provide a greater weight percentage of solids in the reactor. The desired polymer particle size may be achieved by employing a catalyst having particles of a size determined based on the expected catalyst productivity. In certain embodiments, the catalyst particle size may be determined based on the expected catalyst productivity, the polymer particle density, the catalyst particle density, and/or the polymer particle size.

Abstract: Disclosed is a continuous process for producing α,β-unsaturated carboxylic acids or salts thereof, comprising: 1) in a first stage, contacting (a) a transition metal precursor compound comprising at least one first ligand, (b) optionally, at least one second ligand, (c) an olefin, (d) carbon dioxide (CO 2 ), and (e) a diluent to form a first composition; 2) in a second stage, contacting a polyanionic solid with the first composition to form a second composition; and 3) in a third stage, (a) contacting the second composition with a polar solvent to release a metal salt of an α,β-unsaturated carboxylic acid and form a reacted solid. Methods of regenerating the polyanionic solid are described.

Abstract: A method is described that includes contacting an olefin with a catalyst in a polymerization reactor, polymerizing at least a portion of the olefin to form an alpha olefin reaction product, detecting a condition within the polymerization reactor, determining an average temperature of at least one olefin product particle based on the condition, determining an operating particle temperature threshold using a foul curve, comparing the average temperature of the polymer particle to the operating particle temperature threshold, changing one or more operating parameters in response to the comparing, and maintaining the average temperature of the olefin polymer particle at or below the operating particle temperature threshold in response to changing the one or more operating parameters. The alpha olefin reaction product includes a plurality of olefin polymer particles, and the polymerization reactor includes a reaction mixture that includes the olefin, the catalyst, a diluent, and the alpha olefin reaction product.
