Latest Patents

One of his latest patents is titled "High molecular weight polymer with low insoluble gel content." This invention describes treated polymers comprising a polyacrylamide homopolymer or a copolymer with at least 30 mol % acrylamide residue content. The polymers have a weight average molecular weight ranging from 1×10 g/mol to 1×10 g/mol and include 0.1 wt % to 10 wt % of a C1-C6 alkyl ricinoleate. These treated polymer powders dissolve rapidly in water and develop minimal to no insoluble gel upon dilution, making them useful for applications such as flocculation and enhanced oil recovery.

Another significant patent is "Inversion agents for water-in-oil lattices and methods of use." This patent presents water-in-oil lattices made from water-soluble polymers, which include about 15 wt % to 70 wt % polymer solids and one or more alkyl ricinoleates. The addition of C1-C6 alkyl ricinoleates facilitates rapid dilution to less than or equal to 1 wt % polymer solids in a continuous water phase, particularly under challenging conditions.
