    • The invention relates to halogenous polyesters with the recurrent general formula ##STR1## in which at least part of the R's, e.g. 1 to 100 mole-%, preferably 100 mole-%, or 2 to 10 mole-%, are of the general formulas ##STR2## and 0 to 99 mole-%, preferably 0 or 90 to 98 mole-%, of the R's correspond to a phenylene radical and/or a naphthylene radical and/or an alkylene radical of 3 to 10 carbon atoms and/or a cycloalkylene radical, and the R's represent an organic moiety which is contained in bivalent saturated alcohols and corresponds to a branched or unbranched saturated alkylene radical of 2 to 10 carbon atoms and/or to a cycloalkylene radical and/or which is derived from an alkyleneterephthalate containing hydroxyl groups, preferably an oligomeric ethyleneterephthalate and/or an oligomeric propyleneterephthalate and/or an oligomeric butyleneterephthalate, wherein Z represents the groups ##STR3## and X represents hydrogen, bromine or chlorine, wherein at least some of the X's are bromine or chlorine, and in which polyesters, in some cases, a portion of the R's are residues of unsaturated dicarboxylic acid derivatives which, together with ethylenically unsaturated comonomers, preferably styrene, are capable of forming peroxide-curable unsaturated polyester resin (UP resin) solutions, and their preparation as well as their use as fire-retardant molding compositions or articles, and also dicarboxylic acid esters some of which can be used in the preparation of the polyesters as well as the preparation of these dicarboxylic acid esters. Preferably the xylene nucleus in (2) is substituted by Br.sub.4.0 to 2.8 and Cl.sub.0 to 1.2.
