Beschreibung
Zusammenfassung:	Process for preparing an aqueous emulsion of a copolymer of at least one alpha, beta-ethylenically unsaturated monomer, which process comprises polymerizing in an aqueous medium from 99.5 to 30 parts by weight of at least one monomer selected from styrene, alpha -methylstyrene, acrylonitrile, alkyl acrylates, methacrylamine, from 0 to 25 parts by weight of a monomer containing hydroxyl groups, from 0 to 1 parts by weight of a monomer containing amine groups, and from 0 to 15 parts by weight of a monomer containing carboxyl groups, 100 being the total weight parts of monomers, characterized in that the polymerization is carried out substantially in the absence of alkali metal or alkaline earth metal ions.
