    Abstract: 1435162 Flame resistant polyester fibres HOECHST AG 20 July 1973 [22 July 1972] 34663/73 Heading C3R [Also in Division C2] Fibres or filaments are made from a polyester comprising dicarboxylic acid units, diol units and units of the formula in which R is an alkylene, cycloalkylene, arylene or aralkylene radical and R 1 and R 2 are C 1-6 alkyl or an aryl or aralkyl group, and R, R 1 and R 2 may carry substituents or contain hetero atoms. The examples describe fibres of polyesters prepared from dimethyl terephthalate, optionally with dimethyl isophthalate, ethylene glycol or 1,4-butanediol and methylene- or ethylene-di(methylphosphinic acids), phenylene - 1,4 - di(methylphosphinic acid), pxylylene - di(methyl - phosphinic acid), ethylene - 1,2 - di(phenylphosphinic acid)

    Abstract: 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.

    Abstract: Permanently flame-resistant synthetic linear polyesters are obtained by incorporating by condensation into the polyester composed of the usual dicarboxylic acid and diol units an alkylphosphine oxide of the formula WHEREIN THE RADICALS R to R4 represent organic radicals of which R2, R3 and Z may be substituted by 2 hydroxyl groups altogether, R2, R3 and R4 may also represent hydrogen and a is zero or a whole number of from 1 to 4. The flame-resistant polyesters are processed into shaped structures such as fibers, filaments, sheets, injection and compression molded articles characterized by good flameproofness and dyeing properties.
