Abstract

A thermoplastic molding composition comprising a graft polymer is disclosed. The graft polymer contains: The weight average molecular weight of the continuous phase is 130,000 to 275,000 g/mole and the disperse phase is characterized in that its, weight average particle size is less than 0.90 μm. The molding composition is characterized in improved resistance to weathering.
