Title: Indulis Gruzins: Innovator in Polyurethane Technology
Introduction
Indulis Gruzins is a notable inventor based in Louisville, KY (US). He has made significant contributions to the field of polyurethane technology, holding 2 patents that showcase his innovative approach to material science.
Latest Patents
One of his latest patents is titled "Preparation of a pyrithione salt dispersion usable in urethane applications." This invention relates to a stable pyrithione salt polyol dispersion that contains a pyrithione salt(s) in particulate form, a polyol, and a stabilizer such as a rheological additive. The dispersion can be incorporated into existing polyurethane formulations without additional formula adjustment. Polyurethane foams produced from this composition have more open cell structures than those produced with typical commercially available pyrithione salts, providing a soft and comfortable feeling.
Another significant patent by Gruzins is "Polyols containing grafted carboxyl groups and method of making same." This invention focuses on carboxyl-containing monomers for preparing polyurethane polymers. The carboxyl-containing monomers are the reaction product of a low molecular weight polyol compound and an acid anhydride in the presence of 5-500 ppm phosphoric acid. These monomers have a viscosity ranging from 3,000 to 100,000 centipoise and an oligomer content of less than about 30 mg KOH/g. The patent also covers methods for making these carboxyl-containing monomers, as well as prepolymers and urethane polymers that incorporate them.
