Title: Lihong Guo: Innovator in Carboxylic Acid Functionalized Polymers
Introduction
Lihong Guo is a prominent inventor based in Beijing, China. He has made significant contributions to the field of polymer chemistry, particularly in the development of carboxylic acid functionalized polymers. With a total of 11 patents to his name, Guo's work has had a substantial impact on various applications in the industry.
Latest Patents
One of Guo's latest patents is focused on a method of preparing carboxylic acid functionalized polymers. This method involves creating water-soluble, non-peptidic polymers that carry carboxyl functional groups, specifically carboxylic acid functionalized poly(ethylene glycol) (PEG) polymers. The process begins with the reaction of an ester reagent with a water-soluble polymer, leading to the formation of a tertiary ester. This ester is then treated with a strong base in an aqueous solution to produce a carboxylate salt. Finally, the carboxylate salt is converted into a carboxylic acid through treatment with an inorganic acid, resulting in a carboxylic acid functionalized polymer.
