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.
本发明涉及具有循环一般式 ##STR1## 的卤代聚酯,其中至少部分的R,例如1到100摩尔%,优选100摩尔%或2到10摩尔%,为下列一般式之一 ##STR2## 和0到99摩尔%,优选0或90到98摩尔%的R对应于苯基基团和/或萘基基团和/或3到10个碳原子的烷基基团和/或环烷基团,其中R表示有机基团,该有机基团包含双价饱和醇中的一种,并对应于2到10个碳原子的支链或直链饱和烷基团和/或环烷基团和/或源自含有羟基的烷基对苯二甲酸酯,优选为低聚乙烯对苯二甲酸酯和/或低聚丙烯对苯二甲酸酯和/或低聚丁烯对苯二甲酸酯,其中Z表示羟基和/或卤素基,X表示氢、溴或氯,其中至少一些X是溴或氯,并且在某些情况下,这些聚酯中的一部分R是不饱和二羧酸衍生物的残基,这些残基与乙烯基不饱和共聚物(优选为苯乙烯)一起能够形成过氧化物可固化的不饱和聚酯树脂(UP树脂)溶液,以及它们的制备,以及它们作为阻燃成型组合物或制品的用途,以及一些可用于制备聚酯和这些二羧酸酯的制备的二羧酸酯。优选的是(2)中的二甲苯核被Br.sub.4.0至2.8和Cl.sub.0至1.2取代。
