ABSTRACT:
A composition comprising an aromatic carbonate polymer end-capped with a group of the structure ##STR1## wherein --+NR.sub.1 R.sub.2 R.sub.3 is meta or para to the O and R.sub.1, R.sub.2 and R.sub.3 are the same or different and are alkyl of one to three carbon atoms; R is alkyl of one to six carbon atoms, perfluoroalkyl of one to eight carbon atoms, inclusive, phenyl or phenyl substituted with one to three substituents. These substituents can be any of the ordinary substituents which are essentially inert to reaction conditions, such as alkyl, cycloalkyl, alkoxy, phenyl, halo, trifluoromethyl and the like. The alkyl or alkyl group of the alkoxy is generally from one to six carbon atoms, inclusive, branched or normal. Generally, electronegative groups such as fluoro, chloro, bromo and trifluoromethyl are preferred.
