Abstract: Weather resistant thermoplastic ASA compositions comprising (A): 20 to 80 wt.-% of a polymer mixture (A) consisting of: 35 to 65 wt.-% graft copolymer GR1 (D50 of 55 to 170 nm), composed of: 40 to 80 wt.-% cross-linked C1 to C8 alkyl acrylate graft base G11 and 20 to 60 wt.-% SAN-copolymer graft shell G12; and 65 to 35 wt.-% SAN copolymer S1 (MVR 50 to 70 ml/10 min); (B): 5 to 35 wt.-% polymer mixture (B) consisting of: 35 to 65 wt.-% graft copolymer GR2 (D50 of 410 to 1000 nm), composed of: 40 to 80 wt.-% cross-linked C1 to C8 alkyl acrylate graft base G21 and 20 to 60 wt.-% SAN-copolymer graft shell G22; and 65 to 35 wt.-% SAN copolymer S2 (MVR 11 to 25 ml/10 min); (C): 10 to 40 wt.-% of at least one SAN copolymer (C) (MVR 11 to 70 ml/10 min); (D): 1 to 15 wt.-% EVA copolymer (D) (VA > 25 wt.-%); are particularly useful e.g. in the automotive industry.
