The invention discloses a water
solution polymerization production method of dimethyl diallyl
ammonium chloride and
acrylamide copolymer, which uses cation industrial
monomer DMDAAC and industrial non-ionic
monomer AM prepared by industrial one-
step method as raw materials, uses initiator via water
solution polymerization to prepare dimethyl diallyl
ammonium chloride and
acrylamide copolymer, with high relative molecular weight and cation degree
serialization. The invention uses cheap materials, has wide adjustable proportion between oxidant and
reducer in initiator, and the application for initializing
polymerization temperature of different cation degree PDA products. The invention has simple and mild reaction condition, while the PDA product cation degree is 5-99%, relative
characteristic viscosity is 17.0-2.9dL / g, and
residual monomer content is lower than 1%. The product has high cation degree
serialization, high relative molecular weight of PDA product in each cation degree, strong adaptability, simple method, easy industrialization, and wide application in oil development, paper making, mining, weaving, dying,
water treatment, and daily chemical or the like.
