Zusammenfassung:	EN DISPERSIONES POLIMERAS ACUOSAS UN COMPUESTO SE UTILIZA COMO DISPERSOR UN COMPUESTO DE FORMULA QUE TIENE PROPIEDADES ANTIESPUMANTES. SIENDO R1 UN RESTO FENILO, EL RESTO ALQUILO DE CADENA RECTA O RAMIFICADA DE C1 A 18; R2 UN RESTO ALQUILO CON C1 A 8; M UN NUMERO ENTERO DE 0 A 1 Y N UN NUMERO ENTERO DE 3 A 30. Compounds corresponding to the following formula R1-(CH2)m-O-(CH2CH2)n-R2 in which R1 is the phenyl radical or a phenyl radical which is substituted by linear or branched alkyl radicals containing a total of from 1 to 18 carbon atoms, R2 is a C4-C8 alkyl radical, m=0 or 1 and n=3 to 30, are used as dispersants with foam-inhibiting properties in aqueous polymer dispersions and latices.
