Abstract:
    The invention relates to a method for agglomerizing at least one dispersed rubber (A) in an aqueous phase by adding a dispersion of at least one agglomeration polymer (B) in the aqueous phase. The invention is characterised by using an agglomeration polymer as B, containing essentially no free acid groups and by carrying out the agglomerization in the presence of at least one basic electrolyte.
