    Abstract: Graft copolymers comprising a crosslinked, saturated, elastomeric grafting base and a hard shell are prepared by incorporating thermolabile comonomers, as copolymerized units, into the grafting base during the preparation of the latter, in particular at a conversion of from 50 to 90%. During the subsequent grafting of the shell, the conditions used are such that the thermolabile comonomers incorporated as copolymerized units into the grafting base decompose into free radicals. This gives graft copolymers having improved mechanical properties, which copolymers also prove advantageous for the preparation of mixtures with other thermoplastics compatible with the graft copolymers.
