    摘要： This invention relates to a polyester resin comprising (A) from about 5% to about 50% by weight reactive diluent and (B) from about 50% to about 95% by weight of an unsaturated polyester resin prepared from at least one component selected from the group consisting of (i) from about 0.5% up to about 8% by mole of a polyhydric alcohol, having at least three hydroxyl groups, and at least one transesterification catalyst, (ii) from about 2% up to about 12% by mole of a reaction product of a polyol and a fatty carboxylic acid, and (iii) from about 2% up to about 12% by mole of a fatty reactant selected from the group consisting of a fatty primary alcohol, a fatty epoxide, a fatty monocarboxylic acid and mixtures thereof, wherein each member of the group has up to about 100 carbon atoms. In another aspect, the invention relates to mixtures of the above polyester resins with conventional polyester resins. Methods of reducing volatile organic compound emissions are also part of the invention. The present invention provide resins and methods which have low emissions of volatile organic compounds and when used in curable compositions have good gel times and final cured properties.
