<p>The invention relates to a method for agglomerating finely divided rubber latices by adding an aqueous solution of a water soluble amphiphilic copolymer that consists of at least one hydrophilic portion and at least one hydrophobic portion. The inventive method is further characterized in that the molar weight HB of the largest hydrophobic portion and the molar weight HL of the largest hydrophobic portion of the amphiphilic copolymer exceed the following minimum values: HB gt; 500 g mol and HL gt; 2000 g mol.</p> |
