Bromine-containing aromatic modified polyester polyols were synthesized by two-step condensation reactions. Intermediate was synthesized by the esterification of m-bromobenzoic acid with trimethylolpropane in the first step. Polycondensation of the intermediate, 1,4-butanediol, and trimethylolpropane with adipic acid was carried out. Two-component polyurethane coatings were prepared by blending these modified polyester polyols and polyisocyanate. Physical properties of these new coatings were found comparable to non-bromine containing coatings, showing rapid drying character and 18 hours of pot-life. The modified coatings with 30wt% m-bromobenzoic acid also showed a self-extinguishing property
