Title: Innovations of Richard H Backderf
Introduction
Richard H Backderf is a notable inventor based in Richfield, OH (US). He has made significant contributions to the field of polymer chemistry, particularly in the development of polyvinyl chloride (PVC) materials. With a total of 8 patents to his name, Backderf's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is focused on a process for preparing low inherent viscosity-high glass transition materials. This innovation improves various fabrication properties of polyvinyl chloride by treating the resin with a specific enhancing agent. The treatment occurs as a suspension or mass overpolymerization, which reacts at least one high glass transition temperature enhancing agent with a chain transfer agent. This results in a high glass transition temperature-low inherent viscosity agent that significantly enhances the properties of the polyvinyl chloride resin.
Another notable patent involves the creation of flexible overpolymers of vinyl chloride polymers on ethylene copolymers. These flexible elastomers have a Shore A hardness of less than or equal to about 95. The elastomers can be blends of an overpolymer and/or graft polymer with a plasticizer or blending agent, or they can be flexible without the need for such additives. The elastomers are characterized by their Shore A values and haze values of less than or equal to about 50 percent.
