More Information
Summary:Flame-repellant linear polyesters are obtained by incorporating by condensation phosphorus-compounds having the formula O &uarr& HO-P-R-COOH, ¦ R1 wherein R and R1 are organic radicals which may also contain hereto atoms into the linear polyesters, preferably those from terephthalic acid and ethylene glycol. These polyesters are materials of which flame-repellent filaments, fibers, sheets, press-moulded and injection-moulded articles may be made. Products of the invention can be used whereever especially acute risks of ignition and fire exist.
