Abstract: The present invention relates to the production of a polymer powder with improved powder properties, and to its use as impact modifier for rigid polyvinyl chloride (PVC) applications. The impact modifier is composed of emulsion polymer particles which have a core-shell structure, where the shell is composed of a hard polymer and the core is composed of a soft, crosslinked rubber polymer.
