FLAME RETARDING PHOSPHOROUS CONTAINING LINEAR POLYESTERS AND SHAPED ARTICLES THEREOF

摘要

FLAME RETARDING LINEAR POLYESTERS AND SHAPED ARTICLES THEREOF of the disclosure: Flame-repellent linear polyesters are obtained by incorporating by condensation P-compounds having formula , wherein R and R1 are organic radicals which may also contain hetero atoms into the linear polyesters, preferably those from terephthalic acid and ethylene glycol. These polyesters are the materials flame-repellent filaments, fibers, sheets, pressmoulded and injection-moulded articles are made of, these products being used whereever especially acute risks of ignition and fire exist.
