Abstract
The invention relates to thermoplastic polymeric compositions comprising a linear aromatic polyester of a bisphenol and a dicarboxylic acid admixed with a minor proportion of a perfluoroalkenoxy surface active compound. These compositions which are suitable for use as film or molding compositions exhibit enhanced tensile strength on ageing without substantial detriment to other properties of the polyester.
