摘要： The invention provides a living radical polymerization method using a zinc phthalocyanine dye as a near-infrared photocatalyst, including subjecting a free radical polymerizable monomer to a near-infrared light-controlled polymerization reaction, in the presence of a chain transfer agent, a cocatalyst and a zinc phthalocyanine dye containing a carbon-carbon double bond, in a solvent at 0-30° C. under the air atmosphere, to obtain a living radical polymerization product. The free radical polymerizable monomer is an acrylate monomer, a methacrylate monomer, an acrylamide monomer or a methacrylamide monomer; the chain transfer agent includes a thiocarbonate; and the cocatalyst includes an organic amine with or without a carbon-carbon double bond. A near-infrared light-responsive functional zinc phthalocyanine dye is used as a near-infrared photocatalyst for the polymerization reaction, and after the polymerization is completed, the polymerizable zinc phthalocyanine dye remains on the polymer chain by polymerization, thereby realizing the cyclic utilization of the near-infrared photocatalyst.
