Title: The Innovative Journey of William S. Greenlee
Introduction
William S. Greenlee, an accomplished inventor based in Avon Lake, Ohio, has made significant contributions to the field of materials science, holding a total of 16 patents. His work primarily focuses on the development of innovative rigid thermoplastic articles, particularly those made from polyvinyl chloride (PVC) blends that offer enhanced physical properties and aesthetic qualities.
Latest Patents
Among Greenlee's latest patented inventions is a rigid article that boasts a stucco appearance created from a blend of PVC. This innovation features rigid thermoplastic articles that exhibit reduced surface gloss. The reduction in gloss is achieved through a unique mixture of polymers, each possessing different viscoelastic properties. Furthermore, he has developed polyvinyl chloride-acrylate copolymers that are effectively plasticized to achieve a composition characterized by low hardness values. For instance, Shore A hardness values of 55 or less can easily be achieved by utilizing a minimal amount of plasticizer relative to the polymer composition. These advancements enable the production of copolymers with a high acrylate content, contributing to improved flexibility and durability.
