    摘要: A method for producing protective-colloid-stabilized polymers in the form of their aqueous polymer dispersions or in the form of powders which can be re-dispersed in water, wherein one or several monomers from the group made up of vinyl aromatics, 1.3 dienes, acrylic acid esters and methacrylic acid esters of alcohols with 1 to 15 C-atoms are polymerized in the presence of a combination of protective colloids consisting of one or several protective colloids from the group of hydrophobically modified, partly saponified polyvinyl esters which produce a surface tension of ≦40 mN/m as a 2% aqueous solution, and one or several protective colloids which produce a surface tension of >40 mN/m as a 2% aqueous solution.
