    • High assay, reaction-derived decabromodiphenylethane product is prepared by feeding (i) diphenylethane or (ii) partially brominated diphenylethane having an average bromine number less than about two, or (iii) both of (i) and (ii), into the liquid confines of a reaction mixture. Such reaction mixture is (a) formed from components comprised of excess liquid bromine and aluminum-based Lewis acid bromination catalyst, and (b) maintained at one or more elevated reaction temperatures of from about 45°-90°C, and at least when elevated pressure is needed to keep a liquid state in the reaction mixture at the temperature(s) used, the reaction mixture is at such an elevated pressure, whereby arbromination occurs. The feeding is conducted at a rate slow enough to form high assay reaction-derived decabromodiphenylethane product, which is an effective flame retardant.

    • 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.
