Latest Patents
Xiangcheng Pan holds a patent for a process titled "Aqueous ATRP in the presence of an activator regenerator." This patent describes a method for polymerizing radically (co)polymerizable monomers within a temperature range of -10°C to 110°C in an aqueous system. The process 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 an added site-specific functional initiator or a dormant polymer chain that has a radically transferable atom or group. The initial concentration of the soluble catalyst complex in the higher oxidation state is capped at 2500 ppm. The reaction is conducted with the presence of an activator regenerator, ensuring that the mole fraction of the soluble lower activator oxidation state transition metal formed is less than 10%. The resulting polymer chains exhibit a dispersity of less than 1.5.
