Abstract: A process to increase the extension at break of molded articles of thermoplastic compositions comprises filtration of a particulate emulsion polymer having a glass transition temperature below 0 deg C and an average particle size of 50-1000 nm followed by further processing to form the thermoplastic molding composition. A process to increase the extension at break of molded articles of thermoplastic compositions comprising; (A) 1-99 wt.% of a particulate emulsion polymer having a glass transition temperature below 0 deg C and an average particle size of 50-1000 nm; (B) 1-99 wt.% of an amorphous or partially crystalline polymer; (C) 0-50 wt.% of a further thermoplastic polymer; and (D) 0-50 wt.% of a fibrous and/or particulate filler comprises filtration of the dispersion of (A) prepared by emulsion polymerization to remove coagulate followed by further processing to form the thermoplastic molding composition.
