With a total of 2 patents, his work has implications for industrial applications and polymer production efficiency.

Latest Patents

One of Jae-Gon Lim's latest patents is focused on a supported catalyst for producing syndiotactic styrenic polymer with high productivity and significantly reduced reactor fouling. This innovative catalyst comprises a support of organic or inorganic powder with a high surface area, a polymer coated onto the support, and a metallocene catalyst. The polymer contains polar groups that interact with the surface of the support and is insoluble in the styrenic monomer or polymerization solvent during polymerization after the catalyst is loaded. This configuration prevents poisoning of the metallocene catalyst layer by the support layer, resulting in styrenic polymer powder with excellent flowability and morphology.

Another significant patent involves a process for preparing syndiotactic styrenic polymers by recycling products. This process achieves a high conversion rate in the form of fine powder. It includes steps such as preparing styrenic polymers in a solid state, separating a portion of the polymers from the reactor, recycling them, and reacting the recycled polymers with styrenic monomers. The process can utilize a self-cleaning mono- or twin-axis reactor to prevent agglomeration of polymers, enhancing the efficiency of polymerization.
