    摘要: Emulsion polymers which are prepared by free-radical polymerisation of monomers in the presence ofa) polymers of the formulae ##STR1## wherein the radicals have the meanings given in the description, and b) low-molecular anionic emulsifiers,are outstandingly suitable as surface sizes for paper. They are distinguished by a low tendency to foaming and by a wide application spectrum.
