Embodiment 1-5
[0046] By polymerizing diallyl-dimethyl ammonium chloride (DADMAC), acryloyloxyethyl-trimethyl ammonium chloride (ADAM MC Q) and poly(ethylene glycol) methyl ether acrylate (M-PEG acrylates) to synthesize dispersant polymers. The result is an aqueous solution of dispersant with a dry content of dispersant polymer of about 40% by weight.

[0049] *Molecular weight of dispersant polymer determined by GPC
Embodiment 6-8
[0051] Also by polymerizing diallyl-dimethylammonium chloride (DADMAC), acryloyloxyethyl-trimethylammonium chloride (ADAM MC Q) and monofunctional vinyl-terminated ethers and polyethers of different mono Body (m 4 ) to synthesize a dispersant polymer. The monomer composition in all examples was 48.75 mol% DADMAC, 48.75 mol% ADAM MC Q and 2.5 mol% amphiphilic monomer. Here again the result of the polymerization is an aqueous solution of dispersant with a dry content of dispersant polymer of about 40% by weight.
