Abstract

See full text

The present invention provides a “living” radical polymerization method for a vinyl monomer by near-infrared photothermal conversion. The method comprises irradiating a reactor with near-infrared light of 750-850 nm, wherein the reactor has a first chamber and a second chamber that are isolated from each other, the first chamber contains an organic solution of a near-infrared light responsive croconaine dye, and the second chamber is provided with a closed reaction flask containing a reaction solution, the reaction solution comprises a vinyl monomer, two or more of an ATRP initiator, an ATRP ligand, an ATRP catalyst, an RAFT reagent, a thermal initiator, and an additive, and an organic solvent; and the near-infrared light responsive dye converts the near-infrared light into heat energy, by which the reactor is heated to 50-100° C. to polymerize the monomer in the reaction solution, to obtain polymers with controlled molecular weights and molecular weight distributions.
