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: Production of halogen-containing tertiary phosphine oxides of the general formula I R1O PARALLEL ANGLE P-R3 (I) R2 in which the substituents R1, R2 and R3, being identical or different, stand for an alkyl, alkenyl, aryl or aralkyl radical, at least one of those radicals containing at least one aliphatically combined halogen atom. The compounds are made by reacting one or more compounds of the general formula II R4O PARALLEL ANGLE P-R6 (II) R5 in which R4, R5 and R6, being identical or different, stand for an alkyl, alkenyl, aryl or aralkyl radical, at least one of those R4, R5 and R6 radicals containing an aliphatically combined hydroxyl group, with at least equivalent proportions, based on the number of hydroxyl groups, of gaseous hydrogen halide with agitation, if desired, at temperatures within the range about 100 DEG and 300 DEG C; freeing the reaction mixture, during the reaction or after termination thereof, from water originating from the reaction; and separating from the resulting reaction mixture the halogen-containing tertiary phosphine oxide by distillation or crystallization.
