    Abstract: High clarity and ductile molding composition comprising: (a) 71 to 98.99 wt.-% of at least one random copolymer (a) made from 44 to 64 wt.-% of at least one vinylaromatic monomer (a11), and 36 to 56 wt.-%, methyl methacrylate (a12); (b) 1 to 28.99 wt.-% of at least one vinylaromatic-diene block copolymer (b) which comprises at least one hard blocks S made from vinylaromatic monomers and at least one soft block B made from dienes, and/or at least one soft block B/S made from dienes and vinylaromatic monomers; where the proportion of diene-based on entire block copolymer (b) is 47 to 67 wt.-%; (c) 0.01 to 1.0 wt.-% of at least one light stabilizer (c); (d) 0 to 1.0 wt.-% of at least one antioxidant (d); and (e) 0 to 5 wt.-% of one or more additive(s) and/or processing aid(s) (e), different from the light stabilizer(s) (c) and antioxidant(s) (d); have good light stability and processability.
