Abstract: The present invention relates to a polymer powder with improved powder properties, and to its use as impact modifier for polylactic acid. The polymer powder comprises (i) 90.0-99.5 weight%, in particular from 95.0-99.0, of polylactic acid (ii) 0.5-10.0 weight%, in particular from 1.0-5.0 of an impact modifier and (iii) from 0,1 to 2% by weight, in particular from 0,1 to 1% by weight based on the total weight of components (i) to (iii), of a copolymer which comprises epoxy groups and which is based on styrene, acrylate, and/or methacrylate.
