Latest Patents

Valerie holds a patent for her invention titled "Aqueous ATRP in the presence of an activator regenerator." This process allows for the polymerization of radically (co)polymerizable monomers at temperatures ranging from -10°C to 110°C. The method involves a molar excess of a ligand that forms a soluble transition metal complex with an added transition metal salt. This complex participates in a reversible reduction-oxidation cycle with either a site-specific functional initiator or a dormant polymer chain. The initial concentration of the soluble catalyst complex in the higher oxidation state is maintained at or below 2500 ppm, ensuring a controlled reaction environment. The resulting polymer chains exhibit a dispersity of less than 1.5, showcasing the precision of her method.
