Abstract
Described are themoplastic condensation polymers containing a polyhaloaromatic aromatic flame retardant and an aromatic bis-sulfonamide having at least two aromatic rings and from 14 to 30 carbon atoms melt flow improver. These sulfonamides are of advantage in that they have relatively low volatilities at polymer processing temperatures.
