摘要：
A process for the preparation of polymer combinations having high rubber contents from A) aromatic polyesters and B) at least partially cross-linked rubbers, in which1) an aqueous rubber latex having a rubber solids content of up to 65% by weight is mixed with an aqueous alkali metal diphenolate solution and a water immiscible organic solvent in a quantity of from 10 to 1000 parts by weight per 100 parts by weight of rubber in the latex,2) the mixture obtained according to 1) is reacted with dicarboxylic acid halides and/or carbonyl halides and3) the polymer combination is recovered.
