Patent ID: 8158722

Claim:
A composition comprising: A at least one copolymer A composed of a1) at least one alkylated styrene as component A1; a2) acrylonitrile as component A2; and a3) optionally, at least one further monomer as component A3; B at least one block copolymer B composed of b1) at least one block B1 forming a hard phase and composed of at least 15 one vinylaromatic monomer, and b2) at least one block B2 forming a soft phase and composed of at least one vinylaromatic monomer and of at least one diene; C at least one triblock copolymer C composed of c1) a first block C1 composed of at least one vinylaromatic monomer, c2) a second block C2, composed of at least one diene, and c3) a third block C3 composed of at least one methyl methacrylate monomer or comprising at least 50% by weight of methyl methacrylate; and D optionally, at least one styrene polymer selected from glass-clear polystyrene and impact-resistant polystyrene.
