Abstract

Homo- and/or copolymers of one or more ethylenically unsaturated monomers, suitable for the preparation of molded articles that feature improved properties, especially improved fracture properties, heat stability and notched impact strength are disclosed. These homo- and/or copolymers are characterized in that they contain less than 400 particles per m2 of surface area with a diameter greater than 200 μm.
