Latest Patents

Xiwang Zang holds a patent for a novel polycarbonate preparation method. This method involves several key steps: first, mixing a phenoxide water aqueous solution of a bisphenol and/or a polyphenol with phosgene and an inert organic solvent to generate a polycarbonate oligomer. Next, the oligomer is highly emulsified through reinforced micromixing to form a stable emulsion. Finally, this emulsion is introduced into a polycondensation reactor for a chain extending reaction, leading to the separation and final acquisition of the polycarbonate. This method allows for the preparation of high-molecular-weight polycarbonate without the use of catalysts, thereby simplifying the post-treatment process and improving product quality. He has 1 patent to his name.
