Iminodisuccinic acids of the formula ##STR1## the substituents of which have the meaning given in the description, are bleaching regulators in H.sub.2 O.sub.2 bleaching of textile-forming natural plant fibers or silk, wool and their mixtures with synthetics.

Process for the pretreatment of fibers

Copolymers and graft copolymers of perfluoroalkylacrylates or methacrylates and esters of the general formula (I) or (II) ##STR1## wherein R, R.sub.1 and R.sub.2 denote hydrogen or methyl,

Copolymers containing perfluoroalkyls

The invention relates to polyacrylates corresponding to formula (I) ##STR1## to their production in a quasi-ionic polymerization and to their use as monofunctional chain terminators, optionally in combination with typical other chain terminators, for the production of aromatic polycarbonates. The invention also relates to the polycarbonates or polycarbonate mixtures obtained using the compounds corresponding to formula (I) and to their use as additives for other thermoplastic polycarbonates.
