Phosphinated copolyesters based on the acidolysis and polycondensation of (3) with poly(ethylene terephthalate) (PET) were prepared. The crystallinity of copolyesters decreased gradually with the content of (3), as shown in wideangle X-ray diffractograms and differential scanning calorimetry thermograms. Dynamic mechanical analysis and thermalmechanical analysis show Tg increased with the content of (3). UL-94 flame retardant test shows that the flame resistance of PET was enhanced with the content of (3), and a copolyester with UL-94 V-0 grade can be achieved with a phosphorus content as low as 1.43 wt %. |
