Title: The Innovative Contributions of Timothy J Ullman
Introduction
Timothy J Ullman is a notable inventor based in Voorheesville, NY (US). He has made significant contributions to the field of polymer chemistry, holding a total of 8 patents. His work primarily focuses on the development of advanced polycarbonates and their applications.
Latest Patents
One of Ullman's latest patents is titled "Blocked amine terminated polycarbonates and products obtained therefrom." This invention provides a method for creating anhydride terminated polycarbonates or copolymers with various functionalized organic polymers. The process involves using a blocked amino phenol, such as N-t-butoxycarbonyl tyramine, as a chain stopper under interfacial conditions. This allows for the chain stopping of polycarbonate, which can then be processed to yield an amine end group. This end group can react with other polymers or an organic dianhydride to form anhydride terminated polycarbonate. Additionally, Ullman has developed a method for the "Preparation of copolymer from carboxy-functionalized polycarbonate." This involves incorporating a carboxylic acid-substituted phenol, preferably t-butyl p-hydroxybenzoate, as a chain stopper in a polycarbonate-forming reaction. The resulting products can form copolymers with other polymers, such as polyamides and functionalized olefin polymers.
