  • Patent number: 4405738
    Abstract: Polyester polymers and copolyester polymers incorporating flame retardant amounts of cyclotri (or tetra) phosphazenes. These cyclotri (or tetra) phosphazenes can be added at the start of ester interchange, prior to, for example polycondensation and conventional melt spinning, or if desired, after polycondensation but before melt spinning. Specific examples of cyclotriphosphazenes and cyclotetraphosphazenes are hexa(dialkylphosphinylmethyleneoxy)cyclotriphosphazene, octa(dialkylphosphinylmethyleneoxy)cyclotetraphosphazene, tris(alkylphosphinyldimethyleneoxy)cyclotriphosphazene, tetra(alkylphosphinyldimethyleneoxy)cyclotetraphosphazene, hexa(dialkylphosphinylmethylene)cyclotriphosphazene, and octa(dialkylphosphinylmethylene)cyclotetraphosphazene.
