A method is provided for producing protective colloid-stabilized vinyl aromatic-1.3-diene-copolymers in the form of their aqueous polymer dispersions or in the form of a powder which can be re-dispersed in water, by emulsion-polymerizing a mixture containing at least one vinyl aromatic and at least one 1,3-diene in the presence of a protective colloid and optionally, drying the resulting polymer dispersions. In the method part of the protective colloid is provided straightaway and part is metered.

Un método se proporciona para producir el vinilo coloide-estabilizado protector aromatic-1.3-diene-copolymers en la forma de sus dispersiones acuosas del polímero o en la forma de un polvo que se pueda re-dispersar en agua, emulsio'n-polimerizando una mezcla que contiene por lo menos un vinilo aromático y por lo menos un 1,3-diene en la presencia de un coloide protector y opcionalmente, secando las dispersiones del polímero que resultan. En método la parte del coloide protector es straightaway proporcionado y se mide la parte.
