Abstract
A brominated unsaturated polyester resin containing a hydroxyl value of about 35 or less and a hydroxyl acid molar ratio of about 2:1 to about 1:4. The brominated unsaturated polyester resin is prepared from a polyfunctional carboxylic acid, a monocarboxylic acid, and a polyfunctional glycol or alcohol that contains bromine under polyester esterification reaction conditions. The brominated unsaturated polyester resin can be incorporated into a resin composition that also contains vinyl monomer. The invention is also directed to a method of making a brominated unsaturated polyester resin, and to castings, coatings, and laminate panels containing cured brominated unsaturated polyester resin compositions of the invention.
