| abstract | 1522980 Flame retardant polyesters HOECHST AG 13 Nov 1975 [15 Nov 1974] 46883/75 Addition to 1469349 Heading C3R A flame retardant linear polyester is prepared by reacting a dicarboxylic acid/ester, a diol and from 3 to 20 mol. per cent, based on the total acid components, of the cyclic anhydride of a compound of the formula in which R is C1-C15 saturated cyclic or acyclic alkylene radical, an arylene radical or an aralkylene radical and R1 is a C1-C6 alkyl, aryl or aralkyl radical, the cyclic anhydride being added to the reaction mixture in solution in a diol. The examples describe preparing polyesters from dimethyl terephthalate, ethylene glycol or 1,3-propanediol and 2-methyl-2,5- dioxo-1-oxa-2-phospholane dissolved in ethylene glycol. |
