摘要：Graft copolymers comprising a crosslinked, saturated, elastomeric grafting baseand a hard shell are prepared by incorporating thermolabile comonomers, ascopolymerized units, into the grafting base during the preparation of the latter, inparticular 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 ascopolymerized units into the grafting base decompose into free radicals. This gives graftcopolymers having improved mechanical properties, which copolymers also proveadvantageous for the preparation of mixtures with other thermoplastics compatible withthe graft copolymers.
