Title:
FINELY DIVIDED AQUEOUS EMULSION POLYMERS AND USE THEREOF FOR HYDROPHOBIC COATINGS
Document Type and Number:
WIPO Patent Application WO/2016/042116
Kind Code:
A3
Abstract:
The present invention relates to a polymer dispersion which can be obtained by at least one two-stage emulsion polymerization, wherein 1) a polymer A is produced by free-radical polymerization of a first composition, comprising A) at least one monomer, and B) at least one anionic copolymerizable emulsifying agent, 2) the polymer A produced in 1) is mixed with a base, and 3) a polymer B is produced by radical polymerization of a second composition in the presence of the polymer A treated in 2), comprising A) at least one monomer, and B) at least one anionic copolymerizable emulsifying agent. The present invention also relates to a method for producing the polymer dispersion according to the invention, to coating agents in the form of an aqueous composition containing the polymer dispersion according to the invention, and to the use of the polymer dispersion according to the invention for coating materials or paints.
