Title: Innovations by Nam S Ro in Latex Processes
Introduction
Nam S Ro is an accomplished inventor based in Mississauga, Canada. He has made significant contributions to the field of polymer chemistry, particularly in the development of latex processes. With a total of 6 patents to his name, his work has had a notable impact on toner manufacturing.
Latest Patents
One of his latest patents focuses on latex processes, specifically a method for preparing a latex polymer that is consistent with emulsion/aggregation/coalescence (E/A) toner manufacture. This innovative process utilizes a standard latex composition and involves chain-transfer agent partitioning. The emulsion polymerization technique he developed allows for the creation of latex polymers with a wide range of molecular properties. Notably, this process customizes the weight average molecular weight (M) of the latex without significantly altering the number average molecular weight (M), thereby maintaining optimal glass transition temperature (Tg) for good toner performance. In a preferred method, a latex polymer is prepared by mixing a seed particle latex with a second portion of the monomer emulsion and at least one chain-transfer agent, all while using a free-radical initiator and heat. This process is also applicable to core-shell polymerization, making these latex polymers ideally suited for the manufacture of toner and developer for electrophotographic imaging and printing.
