Title: Zhikun Gao: Innovator in Polycarbonate Production

Introduction

Zhikun Gao is a prominent inventor based in Yantai, China. He has made significant contributions to the field of polymer chemistry, particularly in the production of polycarbonate resins. His innovative methods have the potential to enhance the efficiency and quality of polycarbonate manufacturing.

Latest Patents

Zhikun Gao holds a patent for a "Method for preparing branched polycarbonate with continuous two-phase interface phosgene method." This invention describes a process that begins with an aqueous solution of alkali metal hydroxide containing triphenol and polyphenol. This solution reacts with phosgene in the presence of an inert organic solvent to create a prepolymer. Subsequently, a coupling reaction occurs among the prepolymer, an aqueous solution of alkali metal hydroxide with bisphenol, and phosgene, resulting in the final polycarbonate resin. This method effectively avoids cross-linking reactions, reduces production costs, and improves product quality while enhancing the conversion ratio of the branching agent and the branching degree of the final product.
