PCT No. PCT/EP97/04912 Sec. 371 Date Mar. 17, 1999 Sec. 102(e) Date Mar. 17, 1999 PCT Filed Sep. 9, 1997 PCT Pub. No. WO98/12256 PCT Pub. Date Mar. 26, 1998The invention relates to thermoplastic molding compositions comprising A) from 30 to 98% by weight of a graft copolymer comprising aK) from 30 to 90% by weight of an elastomeric graft core, aS) from 10 to 70% by weight of a graft shell comprising aS/1) from 50 to 100% by weight of a styrene compound or a C1-C8-alkyl acrylate or methacrylate, or a mixture thereof, and aS/2) from 0 to 50% by weight of one or more other monomers, B) from 1 to 50% by weight of a thermoplastic polymer and C) from 1 to 70% by weight of an elastomeric block copolymer prepared by anionic polymerization of the monomers with addition of a potassium compound soluble in non-polar solvents (Step 1) followed by hydrogenation of all or virtually all the olefinic double bonds of the polymer obtained in Step 1, as described in greater detail herein.
