Flexibly Tethered Dinuclear Zinc Complexes: A Solution to the Entropy Problem in CO2/Epoxide Copolymerization Catalysis?

摘要

World-wide research activities over the last decade have demonstrated that carbon dioxide is a valuable carbon source for a series of chemical products. One very promising class of products is aliphatic polycarbonates, synthesized by the reaction of carbon dioxide and epoxides. These polymers show interesting properties, as they are biodegradable, highly transparent, UV stable, and have a high Young's modulus. Latest research even led to isotactic poly(cyclohexene carbonates), opening a route to semi-crystalline thermoplastic materials.
