摘要：
Molding materials having stress cracking resistance containingA) from 49 to 99% by weight of a polymer obtainable by polymerizing a C.sub.1 -C.sub.20 -alkyl ester of methacrylic or acrylic acid or a mixture of said esters,B) from 0.95 to 50% by weight of a polymer obtainable by polymerizing a monomer mixture comprisingb.sub.1) from 75 to 82% by weight of a vinyl aromatic monomer andb.sub.2) from 18 to 25% by weight of acrylonitrile or methacrylonitrile or a mixture thereof, andC) from 0.05 to 1% by weight of a mixture containingc.sub.1) a triaryl phosphite of the formula I ##STR1## c.sub.2) an amine of the formula II ##STR2## where n is from 2 to 10, c.sub.3) a benzotriazole of the formula III ##STR3## and C.sub.4) a phenol.
