Abstract

The use of alkyl glycosides of C.sub.8 -C.sub.22 alkanols and reducing sugars, in which one sugar chain containing on average from 1 to 10 sugar residues attached to one another by glycoside bonds is present for every alkyl group, as co-emulsifiers or emulsifiers in the emulsion polymerization of ethylenically unsaturated monomers.
