Process for obtaining impact resistant grafted thermoplastic copolymers, characterized in that it comprises polymerizing by means of free radical forming catalysts in the presence of A) 5 to 30% by weight, based on the solids content of an emulsion of a saturated copolymer of 1 to 30% by weight of p-isopropyl- α methylstyrene and 99 to 70% by weight of an ether selected from the group consisting of acrylic acid ester and methacrylic acid, as the base of the graft, B) 95 to 70 % by weight, on the basis of the solids content, of at least one monomer having a terminal group CH2 = C which itself forms hard and brittle polymers, it being necessary that the base of graft A contain a quantity of p- isopropyl- α -methylstyrene such that the proportion of this body in the graft copolymer amounts to at least 0.3% by weight.
