Title: Innovations of Xiaoyan Tang in Biodegradable Polymers
Introduction
Xiaoyan Tang is an accomplished inventor based in Fort Collins, Colorado. He has made significant contributions to the field of biodegradable polymers, holding three patents that showcase his innovative approaches to polymer synthesis.
Latest Patents
Tang's latest patents focus on the synthesis of polymers from cyclic diolides. These patents describe biodegradable polymers with advantageous physical and chemical properties, as well as methods for their production. One notable embodiment details a new chemical synthesis route to the technologically important biodegradable poly(3-hydroxybutyrate) (P3HB). This method achieves high isotacticity and molecular weight, which are essential for practical applications. The new synthesis route utilizes racemic eight-membered cyclic diolide (rac-DL), meso-DL, or a mixture of both, derived from bio-sourced dimethyl succinate. Additionally, enantiomeric (R,R)-DL and (S,S)-DL are optically resolved using metal-based catalysts. The use of a stereoselective racemic molecular catalyst allows for the rapid production of P3HB under ambient conditions, resulting in a polymer with essentially perfect isotacticity, high crystallinity, and a melting temperature of 171°C. The polymer also exhibits high molecular weight and low dispersity.
