A thermally stable phosphonium-based compound, butyl p-carboxyphenyl diphenylphosphonium bromide, has been synthesized and is stable up to 317 °C (TGA 10 °C per min). High thermal stability facilitates the survival of these salts in a high temperature synthesis or application. Poly(ethylene terephthalate)-co-poly(ethylene isophthalate) (PET-co-PEI) ionomers with 1.3 to 7.7 mol percent phosphonium end-capping agent were synthesized. Melt rheology confirmed weak association of phosphonium groups, suggesting facile processing.
