Title: The Innovations of Robert W. Simmons
Introduction
Robert W. Simmons is a notable inventor based in Midland, MI (US), recognized for his contributions to the field of chemical formulations. With a total of two patents to his name, Simmons has made significant advancements in aerosol technology and fabric treatment solutions.
Latest Patents
Simmons' latest patents include a formulation for a methylene chloride stabilizer designed for use in aerosols. This innovative formulation utilizes certain substituted succinic acids, such as sodium alkenyl succinate, and substituted imidazoline derivatives, like ethoxypropionic acid imidazoline. These components provide corrosion resistance for tin-plated steel and enhance solvent stability in aerosol formulations that contain alcohol, methylene chloride, and water, using a hydrocarbon as the propellant. Another significant patent focuses on an anti-snag finish that is soluble in non-aqueous solvents. This invention reduces fabric snagging by treating the fabric with an organic solvent solution of a copolymer made from hydroxyalkyl acrylate, acrylonitrile, alkyl acrylate, and acrylic acid. The preparation of this organic solution involves solution polymerizing the specified monomers in an organic reaction solvent, such as a mixture of toluene and n-butanol, followed by stripping the reaction solvent and dissolving the polymerized product in an organic application solvent like perchloroethylene or 1,1,1-trichloroethane.
