Title: Innovations by Lance Walter Lewis

Introduction

Lance Walter Lewis is an accomplished inventor based in Hartville, OH (US). He has made significant contributions to the field of polymer technology, particularly in the development of processes for creating dry resins from emulsion polymerized latex. With a total of 2 patents to his name, Lewis continues to push the boundaries of innovation in his field.

Latest Patents

Lewis's latest patents focus on a process for finishing latex to form a dry resin and the resulting product. The first patent describes a method that includes coagulating a latex of a thermoplastic polymer at a temperature at or just above the agglomeration temperature of the resin. This process involves dewatering the resin slurry to form a resin cake, drying the resin cake using extrusion technology to create a resin melt, and solidifying the resin melt to form the final resin product. The preferred processes also include finishing the resin through methods such as pelletizing and grinding. Additionally, the invention emphasizes the importance of collecting and neutralizing aqueous liquid byproducts from the dewatering and drying steps. The dried resins produced can have a moisture content of not greater than 1.0% by weight and a residuals concentration of not greater than 500 ppm.
