Title: **Robert W Campbell: Innovator in Polymer Chemistry**
Introduction
Robert W Campbell, a prolific inventor based in Bartlesville, OK, has made significant contributions to the field of polymer chemistry. With an impressive portfolio of 28 patents, his innovations focus primarily on the development of arylene sulfide polymers and melt stable phenylene sulfide/sulfone polymers.
Latest Patents
Among his latest patents is a unique process for the production of arylene sulfide polymers. This innovative method involves subjecting a mixture of at least one first sulfur source, one second sulfur source that is an organic monothiol compound, a polyhalo-substituted aromatic compound, and a polar organic compound to specific polymerization conditions. The introduction of the organic monothiol compound prior to the completion of polymerization allows for the production of arylene sulfide polymers with enhanced extrusion rates.
Another notable patent focuses on melt stable phenylene sulfide/sulfone polymers. This invention outlines a method for creating a highly stable polymer by redissolving a previously produced phenylene sulfide/sulfone polymer in N-methyl-2-pyrrolidone, then combining this solution with an alcohol of one to four carbon atoms (such as methanol or ethanol) to precipitate the polymer in a particulate form. This method results in a product with remarkable melt stability.
