Polymers or copolymers of diallylamine derivatives of the formula, CH2=CR1-CH2+R2 ANGLE N ANGLE CH2=CR1-CH2R3 Y<-> wherein R1 is hydrogen or methyl: R2 and R3 are independently hydrogen, allyl, methallyl, straight-chain or branched-chain alkyl having 1-16 carbon atoms, phenylalkyl or hydroxyalkyl of the formula, HO-(-CH2-)m-, in which m ia an integer of 1-6 or R2 and R3 may form together with the adjacent N atom pyrrolidyl, piperidyl or morpholino; and Y is halogen or inorganic acid anion, are produced by conducting photopolymerization of a solution or slurry of at least one diallylamine derivative mentioned above with or without other comonomer such as maleic anhydride, maleic acid, or a vinyl compound, with irradiation of light having wavelengths of 150-500 m mu . The polymerization rate can be accelerated in the presence of a special sensitizer such as benzophenone or acetophenone together with hydroquinone, dioxane, morpholine or derivative thereof, or a charge-transfer complex of sulfur dioxide and a diallylamine derivative.
