The invention relates to a method for preparing a vinyl ether polymer by photo-initiated polymerization, which comprises the step of: under a protective atmosphere, performing photo-initiated polymerization on a vinyl ether monomer in the presence of an organic halogenated hydrocarbon and manganese carbonyl under irradiation of light having a wavelength of 365-550 nm at −25° C. to 25° C., to obtain a vinyl ether polymer after the reaction is completed. In the method, a vinyl ether monomer is subjected to cationic polymerization in the presence of manganese carbonyl and an organic halogenated hydrocarbon under visible light, to prepare a vinyl ether polymer with controlled molecular weight and narrow molecular weight distribution.
