Latest Patents
Zhansen Xiong 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, another aqueous solution of alkali metal hydroxide with bisphenol, and phosgene, ultimately yielding a high-quality polycarbonate resin. This method effectively avoids cross-linking reactions, reduces production costs, and improves the conversion ratio of the branching agent.
