POLYMER DISPERSION WITH THEREOF APPLICATION IN HIGH PIGMENT VOLUME CONCENTRATION PAINTS

摘要

Provided is a dispersion of polymer particles comprising, as polymerized units, by dry weight based on total dry weight of the polymer particles, from 85％ to 99.9％ ethylenically unsaturated nonionic monomers, from 0.01％ to 4％ phosphorous-containing (meth) acrylate monomers, and at least one neutralizer. The final pH of the polymer dispersion is above 6, and from 50％ to 100％ by mole of the total neutralizers are alcohol amines. It further provides a paint comprising said dispersion. The paint has both satisfactory paint viscosity stability and improved paint performances such as scrub resistance, stain resistance, corrosion resistance and durability.
