Abstract

This invention relates to graft polymers of the ABS type which are produced in emulsion, and to thermoplastic molding compositions which are based thereon and which exhibit a very considerably increased notched bar impact strength compared with known ABS molding compositions and which at the same time exhibit high hardness values or high modulus values and good thermoplastic processability.
