Title: Qimin Jiang: Innovator in Polymer Chemistry

Introduction

Qimin Jiang is a prominent inventor based in Changzhou, China, known for his significant contributions to the field of polymer chemistry. With a total of seven patents to his name, Jiang has developed innovative solutions that enhance the efficiency and sustainability of polymer production.

Latest Patents

One of Jiang's latest patents is focused on an itaconic acid-based multifunctional surfactant and its preparation method. This invention relates to a polymerizable surfactant with reducibility, which is synthesized through a reaction between an acid anhydride and a long-chain fatty alcohol. The resulting intermediate is then reacted with the hydrochloride of dimethylaminohalogenated alkane, leading to a surfactant that serves as a reactive emulsifier. This surfactant can copolymerize with monomers to create a soap-free emulsion, significantly reducing energy consumption during production. Additionally, it enables one-step emulsion polymerization at normal or low temperatures, resulting in environmentally friendly emulsions with excellent properties.

Another notable patent involves a process for preparing ultra-high molecular weight polymers via emulsion polymerization at room temperature. This method utilizes persulfate as an initiator and anionic surfactants as emulsifiers, allowing for free radical polymerization without the need for additional initiators. The resulting ultra-high molecular weight polymers can achieve weight average molecular weights exceeding 1,000,000 g/mol, with high monomer conversion rates.
