    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: PROCESS FOR THE MANUFACTURE OF FLAME RETARDING LINEAR POLYESTERS of the disclosure: In an improvement of the process of Patent Application Serial No. 209 323 , according to which flame retarding linear polyesters are manufactured by reaction of dicarboxylic acidscapable of forming high molecular weight linear polyesters or the esters thereof with lower aliphatic alcohols, with diols, and phosphorus compounds of the formula or the esters thereof with lower aliphatic alcohols or also the cyclic anhydrides thereof, the cyclic anhydrides are used after having been dissolved previously at elevated temperature in a diol suitable for the polyester manufacture, preferably in the diol used as main component. The symbols of the formula have the following meanings: R = saturated open-chain or cyclic alkylene, arylene or aralkylene, R1= alkyl having up to 6 carbon atoms, aryl or aralkyl; R as well as R1 optionally containing 1 or more hetero atoms, preferably F, Cl, Br, O or S. By dissolving the cyclic carboxyphosphinic acid anhydrides in a diol before adding them to the polyester manufacturing batch the formerly necessary comminution of the hydroscopic cyclic anhydrides with absolute exclusion of moisture may be omitted, and furthermore it is possible to expose the anhydrides to the elevated polycondensation temperatures for a short time only.
