Abstract: The invention is directed to a thermoplastic recycling molding composition comprising recycled acrylonitrile-butadiene-styrene copolymer (r-ABS) as component A and virgin material as component B, wherein the component B is a mixture of at least two components selected from virgin thermoplastic polymers B1 and virgin lubricants B2, or wherein the component B is one or more polymer selected from polymers which are not homogenously miscible with rABS. Further, the present invention is directed to a process for the preparation of the thermoplastic recycling molding composition.
