Process for making unsaturated, thermosetting, brominated phthalic anhydride/polyol polyester resins |
摘要 |
Unsaturated, thermosetting, brominated phthalic anhydride/polyol polyester resins are prepared by reacting brominated phthalic anhydride with polyol and an unsaturated polycarboxylic acid compound in the presence of an acid neutralizing agent under reaction conditions so as to form an unsaturated polyester resin product, the proportions of reactants being selected so as to provide, (i) at least about a 5:4 mole ratio of total moles of polyol to the sum of the moles of brominated phthalic anhydride, unsaturated polycarboxylic acid compound and any saturated polycarboxylic acid compounds in the reaction, and (ii) a bromine content of at least about 40 weight percent in the unsaturated polyester resin product.
