Application of 2-acryloyl-2-methylpropylphosphonic acid-acryloylmorpholine copolymer

2-acryloyl-2-methylpropylphosphonic acid-acryloylmorpholine copolymer

[Structural formula]

[Physical and chemical properties] Light yellow transparent aqueous solution, pH value is about 4, solid content is 30%

[Preparation method] The synthesis of the polymer is generally divided into two steps: functional monomer preparation and solution polymerization

(1) Improved preparation method of 2-acryloyl-2-methylpropionic phosphoric acid monomer

The improved synthesis method of 2-acryloyl-2-methylpropanephosphonic acid (AMPP) is to change the dechlorination agent from phosphorus pentoxide to sulfur dioxide.

①Preparation of 2-methyl propylene phosphonic dichloride Weigh 208.

②The hydrolysis of dichloride Weigh 86.

③Synthesis of 2-acryloyl-2-methylpropronic acid Weigh 34.

(2) Synthesis of polymer

Take 2-acryloyl 2-methyl propyl phosphoric acid and acryloyl morpholine with a molar ratio of 1.

[Application] Because of the introduction of phosphonic acid groups in the macromolecular chain, this product has good scale and dispersion and corrosion inhibition capabilities, and contains morpholine groups with tertiary amine structure, so the copolymerized product has a certain sterilization effect
