Abstract

A thermoplastic molding material consists of PA1 A) 30-80% by weight, based on A+B, of an elastomeric grafting base A defined in more detail and PA1 B) 20-70% by weight, based on A+B, of a shell grafted onto the grafting base A and defined in more detail and PA1 C) 0.001-1 part by weight, based on 100 parts by weight of A+B, of .alpha.-tocopherol and PA1 D) from a half to ten times the amount, based on C, of a thiodipropionic ester selected from dilauryl and distearyl thiodipropionate.
