Title: The Innovations of Leon Edward Newman

Introduction

Leon Edward Newman is an accomplished inventor based in Emmaus, Pennsylvania. He is known for his significant contributions to the field of high-performance paints through his innovative patent. His work has had a lasting impact on the formulation of paints, particularly in the use of vinyl acetate emulsions.

Latest Patents

Newman holds a patent for "Vinyl acetate emulsions for high scrub paints." This invention relates to improved vinyl acetate-ethylene emulsions that allow for the formulation of high-performance paints without the need for coalescing solvents. The latexes developed from this invention are based on copolymers of vinyl acetate and ethylene, which may also include comonomers such as alkyl acrylates or methacrylates. The resulting paints are characterized by having substantially no insolubles, with resin particles in the emulsion having a particle size ranging from 0.2 to 0.35 microns. This innovation ensures that a small percentage of the total number of particles in the latex exceed 0.35 microns, while another small percentage is smaller than 0.2 microns. The resin particles are essentially monodisperse, and the use of ethylene as a low Tg monomer results in resin particles with a Tg ranging from minus -5 degrees to 8 degrees Celsius. The improved process for producing the emulsion includes the formation of a seed latex, followed by the polymerization of monomers in the presence of the seed.
