Fremgangsmåte ved fremstilling av en vandig polymerdispersjon ved emulsjonspolymerisasjon hvori minst en monomer inneholdende en fosforsyre, nulfonayre eller karbok8ylsyregruppe eller emulgerende gruppe foreligger, minst et emulgerlngsmiddel er tilstede og i hvilken minst en forbindelse inneholdende en polyoksyetylenkjede med 60 til 400 oksyetylenenheter foreligger val-gt fra gruppen polyoksyetylenglykoler, emulgerlngs-midler inneholdende en polyoksyetylenkjede og kopolymeriserbare monomerer Inneholdende en polyoksyetylenkjede. Denne dispersjon er meget egnet for bruk i høyglansaralinger. The invention concerns a process for the production of an aqueous polymer dispersion by emulsion polymerisation wherein at least one monomer containing a phosphoric acid, sulphonic acid or carboxylic acid group or emulsifying group is present, at least one emulsifier is present and in which at least one compound containing a polyoxyethylene chain of 60 to 400 oxyethylene units is present chosen from the group of polyoxyethylene glycols, emulsifiers containing a polyoxyethylene chain and copolymerisable monomers containing a polyoxyethylene chain. Said dispersion is very suitable for use in high-gloss paints.
