Title: Thomas H. Sutherland: Innovator in Polyvinyl Chloride Technologies
Introduction
Thomas H. Sutherland, based in Sarnia, Canada, is a notable inventor with two significant patents in the field of polymer chemistry. His work primarily focuses on enhancing the properties of polyvinyl chloride (PVC) resins, contributing advancements that benefit various industrial applications.
Latest Patents
Sutherland's latest patents include methodologies for improving the impact strength and processing characteristics of rigid vinyl halide polymers. His first patent details a process where the impact strength of these polymers is greatly enhanced by graft-blending up to 50 parts by weight of a butyl rubber composition with one hundred parts of vinyl chloride monomer. This innovative approach involves polymerizing vinyl chloride monomer alongside the butyl rubber using suspension polymerization techniques, achieving a remarkable balance of impact enhancement without compromising other essential properties like processability.
In his second patent, Sutherland describes the preparation of a high bulk density/low porosity polyvinyl chloride resin. This resin exhibits high processability and thermal stability, synthesized through a meticulous suspension polymerization process. It incorporates components such as hydroxyethyl cellulose, butyl stearate as a lubricant, and lauryl peroxide as a water-insoluble initiator, all performed under specific low-shear conditions and minimal oxygen presence.
