摘要:
The invention relates to a method for producing polymeric solids free of auxiliary emulators starting from polymer latices (dispersion), wherein a polymer dispersion with a starting ph-value greater than 9 is set to a ph-value of 6 to 9 by adding gaseous carbon dioxide and the polymer dispersion is subsequently coagulated by shearing and/or freezing.
