The invention relates to the use of polyphosphonates, copoly(phosphonate ester)s, copoly(phosphonate carbonate)s, and their respective oligomers, as flame retardant additives for polyester fibers to impart fire resistance while maintaining or improving processing characteristics for melt spinning fibers.

Phosphonate polymers, copolymers, and their respective oligomers as flame retardants for polyester fibers

The invention relates to the use of amino terminated phosphonamides and their oligomers, as flame retardant additives for a variety of polymers to impart flame retardancy while maintaining or improving processing characteristics and other important properties.

Amino terminated phosphonamide oligomers and flame retardant compositions therefrom

Polyester co-polyphosphonates including of phosphonates covalently incorporated with polyesters and methods for making such polyester co-polyphosphonates are described herein. The polyester co-phosphonates and compositions prepared from these compounds exhibit an excellent combination of processing characteristics, mechanical and fire resistant properties.

Polyester co-phosphonates

Disclosed are polymer compositions including polycarbonates, polyphosphonates, copoly(phosphonate carbonate)s, and organic salts and/or silicone containing compounds that exhibit a superior combination of properties compared to prior art.

Polyphosphonate and copolyphosphonate additive mixtures

Thermoplastic polyurethanes (TPUs) formulations including phosphonate oligomers, phosphonate co-oligomers, phosphonate polymers, or phosphonate containing copolymers which exhibit an excellent combination of properties including optical transparency and melt flow without significant reduction in other important physical or mechanical properties and exceptional fire resistance are described herein.
