Definitions
- 6,238,521 teaches to add coagulants (such as starch, low molecular weight cationic synthetic polymers, alum), to add a cationic dispersion polymer which is a copolymer comprising about 30 mole % of DADMAC (diallydimethylammoniumchloride) and about 70 mole % Acrylamide before shearing.
- a cationic dispersion polymer which is a copolymer comprising about 30 mole % of DADMAC (diallydimethylammoniumchloride) and about 70 mole % Acrylamide before shearing.
- mieroparticles selected from the group consisting of copolymer(anionic) of acrylic acid and acrylamide, bentonite, dispersed silica are added.
- R4 is hydrogen atom or methyl
- the polymerization, copolymerization, terpolymerization is carried out in an aqueous salt solution which can dissolve the monomers used, but does not dissolve the resulting polymer, copolymer, or terpolymer with stirring and in the presence of a dispersant which is mixture of PEI(Poly Ethylene Imine) and SMA(Styrene Maleic Anhydrous).
- a dispersant which is mixture of PEI(Poly Ethylene Imine) and SMA(Styrene Maleic Anhydrous).
- PAC Poly Aluminum Chloride
- the process requires to use cationic or anionic monomer plus non ionic acrylated monomer and PEI(Polyethyleneimine),SMA(Stayrene Maleic Anhydride), non ionic surfactant mixture as dispersants in the anionic salt solution under the existence of free radical initiator.
- PEI Polyethyleneimine
- SMA Stayrene Maleic Anhydride
- non ionic surfactant mixture as dispersants in the anionic salt solution under the existence of free radical initiator.
- the product from this invention is to be used as retention, drainage aids in papermaking or oil-water emulsion breaker, or solid liquid separator in various types of wastewater treatment
- the salt concentration of the aqueous solution is 21 -25% by weight of polyvalent anionic salt.
