Cationic polyacrylamide was synthesized in aqueous solution using 2-methylacryloyloxyethyltrimethyl methylpropionconidine)dihydro chloride(V-50) as initiators by assistance of photo-initiation using a metal halide light. The effects of polymerization factors, such as monomer concentration, initiation temperature, initiator concentration, pH and m (DMC) : m (AM), on the intrinsic viscosity and solubility of product were studied. Under the conditions of monomer mass fraction 30%, m (DMC) : m (AM) = 10 ～ 30:90 ～ 70, initiator concentration 0. 0048 %, pH = 4, initiation temperature 15 ℃, the intrinsic viscosity of obtained product was ≥ 10 dL/g and the dissolving time was ≤ 40 min. The structure of copolymer was characterized by infrared spectroscopic (IR).
