Title: The Innovations of William R Coutant
Introduction
William R Coutant is a notable inventor based in Stillwater, OK (US). He has made significant contributions to the field of polymer science, particularly in the development of ethylene copolymers. With a total of 17 patents to his name, Coutant's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is titled "Olefin polymers, method of making, and use thereof." This invention focuses on PE-100 ethylene copolymers and the pipes made from them, which exhibit a Tabor abrasion loss between about 0.01 and about 0.001 grams per 1000 revolutions. The copolymers are created by reacting ethylene with at least one mono-1-olefin comonomer, which contains between 2 to about 10 carbon atoms. The process occurs in a reaction zone under specific polymerization conditions, utilizing a hydrocarbon diluent, a catalyst system, and a cocatalyst. The comonomers can include various mono-1-olefins, such as 1-hexene, 1-butene, 4-methyl-1-pentene, 1-octene, and 1-decene. These ethylene copolymers are particularly useful for producing PE-100 pipes that maintain structural integrity without sagging, even in larger diameters exceeding 42 inches. Another significant patent involves "Phosphite additives in polyolefins," which enhances the whiteness and stability of polyolefins after processing through the addition of a combination of high activity phosphite and hydrolytically stable phosphite.
