Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a high molecular polymer intermediate production device and process flow. Background technique [0002] High molecular polymers are widely used in petrochemical, papermaking, textile printing and dyeing, and daily chemicals, especially as a flocculant in water treatment, sludge dehydration and other fields, and have attracted much attention from manufacturers. The demand is increasing year by year, and the prospect is good. Polymerization of cationic monomers such as quaternary ammonium salts, quaternary phosphonium salts and quaternary sulfonium salts is the main way of polymer production. 2) The mechanical force resistance of cationic polymers to form flocs is far superior to that of DMC flocculants, and has become the most widely used and most used polymer flocculant product. DA (dimethylaminoethyl acrylate, [CAS registration number] 2439-35-2, hereinafter referr...
