Title: The Innovations of William E. Lenney
Introduction
William E. Lenney is a notable inventor based in Allentown, PA, with a remarkable portfolio of 14 patents. His work primarily focuses on advancements in polymer chemistry, particularly in the development of graft emulsion copolymers.
Latest Patents
One of his latest patents is for poly(vinyl alcohol)-g-polyethylene graft emulsion copolymers. This invention involves aqueous-based graft emulsion copolymers that comprise a polymer with multiple hydroxyl groups, specifically a vinyl alcohol homo- or copolymer, which is grafted with polyethylene. The process includes polymerizing ethylene and potentially other ethylenically unsaturated monomers in an aqueous solution of a polymer with hydroxyl groups. The resulting graft emulsion copolymer can contain polyethylene ranging from 50 to 95 wt%, with the hydroxyl-containing polymer making up 5 to 50 wt%, and up to 45 wt% of another polymerized ethylenically unsaturated monomer. The polymerization occurs in an aqueous solution containing at least 5 wt% of a hydroxyl-containing polymer with a degree of polymerization between 50 and 2200.
Another significant patent involves saturant binder systems for high-performance air and oil filters. These filters utilize a basestock that is impregnated with an aqueous-based poly(vinyl alcohol) graft emulsion copolymer as a binder. This binder is created by graft polymerizing one or more ethylenically unsaturated monomers in an aqueous poly(vinyl alcohol) solution, where at least 30% of the total poly(vinyl alcohol) is 70 to 97 mol% hydrolyzed.
