Title: Innovations of Jianan Guan in Polycarboxylic Acid Research
Introduction
Jianan Guan is a prominent inventor based in Beijing, China. He has made significant contributions to the field of polycarboxylic acid research, holding a total of 2 patents. His work focuses on developing innovative methods for preparing temperature and pH-responsive polycarboxylic acids.
Latest Patents
Jianan Guan's latest patents include a method for preparing end-group functionalized comb structure polycarboxylic acid. This method utilizes temperature and pH-responsive monomers, unsaturated halogenated hydrocarbons, and small carboxylic acid monomers to create a polycarboxylic acid material through self-polymerization, substitution, and copolymerization. The process begins with the self-polymerization of temperature/pH-responsive monomers to form a polymer chain with end-group functionalization. Subsequently, substitution with unsaturated halogenated hydrocarbons yields macromonomers, which are then copolymerized with small carboxylic acid monomers to produce a comb structure polymer featuring a polycarboxylic acid main chain and temperature/pH-responsive side chains.
Another notable patent involves a preparation method for temperature/pH-responsive polycarboxylic acid. This method employs acrylic ester and temperature/pH-responsive monomers to synthesize polycarboxylic acid via acrylate monomer self-polymerization, grafting, and hydrolyzation. The process utilizes acrylate as the reaction monomer to polymerize polyacrylate with controllable molecular weight, followed by copolymerization with temperature/pH-responsive monomers to create graft copolymers. The final product is hydrolyzed to yield a comb structure temperature/pH-responsive polycarboxylic acid.
