摘要：
The present invention relates to phthalimide compounds of the formula (I) ##STR1## wherein X denotes H or halogen, for example chlorine or bromine,a and b independently of one another denote 0 or 1 andR denotes a C.sub.1 -C.sub.4 -alkyl radical,which, in combination with alkali metal salts, are suitable as flameproofing agent combinations for thermoplastic, branched, aromatic polycarbonates, and the preparation of these compounds.
