    • A flame retardant formulation which is the combination of at least (1) at least one bromine-containing polyol flame retardant formed from the reaction of (a) tetrabromophthalic anhydride, (b) an aliphatic polyol, and (c) an epoxide, and (2) at least one aliphatic diester of an alkane dicarboxylic acid, with the proviso that the formulation has a viscosity at 25°C of about 20,000 cps or less, and a bromine content of at least about 40 wt%. A flame retardant compound formed from A) tetrabromophthalic anhydride; B) diethylene glycol; C) at least one alpha-omega alkane diol, or at least one alpha-omega alkane diol and at least one aliphatic monool; and D) at least one alkylene oxide; with the proviso that the compound has a viscosity at 25°C of about 60,000 cps or less, and a bromine content of at least about 43 wt%. Polymer compositions formed from (a) a polyurethane or a polyisocyanurate and (b) a formulation of the invention. One process to make a formulation involves heating a mixture of (a), (b), and at least one liquid aliphatic diester of a alkane dicarboxylic acid to form an intermediate composition; and then the intermediate is contacted one or more times with (c) thereby producing the formulation. Optionally, excess (c) is removed.
    • 阻燃剂组合物,其是由(a)四溴邻苯二甲酸酐,(b)脂族多元醇和(c)环氧化物的反应形成的至少(1)至少一种含溴多元醇阻燃剂和(c) 2)烷烃二羧酸的至少一种脂族二酯,条件是制剂在25℃下的粘度为约20,000cps或更低,溴含量为至少约40重量%。 由A)四溴邻苯二甲酸酐形成的阻燃化合物; B)二甘醇; C)至少一种α-ω链烷二醇,或至少一种α-ω链烷二醇和至少一种脂族一元醇; 和D)至少一种环氧烷; 条件是该化合物在25℃下的粘度为约60,000cps或更低,溴含量为至少约43重量%。 由(a)聚氨酯或聚异氰尿酸酯和(b)本发明的制剂形成的聚合物组合物。 制备制剂的一个方法包括加热(a),(b)和至少一种烷烃二羧酸的液体脂族二酯的混合物以形成中间体组合物; 然后将中间体与(c)一次或多次接触,从而制备制剂。 任选地,除去过量(c)。
