    • 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.
    • 本发明涉及一种聚酯树脂,其包含(A)约5重量%至约50重量%的反应性稀释剂和(B)约50重量%至约95重量%的不饱和聚酯树脂,其由至少一种选自 由(i)约0.5%至约8%摩尔的具有至少三个羟基的多元醇和至少一种酯交换催化剂,(ii)约2%至约12%由 摩尔多元醇和脂肪羧酸的反应产物,和(iii)约2%至约12%摩尔的脂肪族反应物,其选自脂肪族伯醇,脂肪环氧化物,脂肪族 单羧酸及其混合物,其中该基团的每个成员具有至多约100个碳原子。 另一方面,本发明涉及上述聚酯树脂与常规聚酯树脂的混合物。 减少挥发性有机化合物排放的方法也是本发明的一部分。 本发明提供具有低挥发性有机化合物排放的树脂和方法,并且当在可固化组合物中使用时具有良好的凝胶时间和最终的固化性能。

    • A thermoplastic multiphase composition is provided which is a melt blend of a functionalized block or graft copolymer and a polyamide. The blend is made from polymers. That is, an elastomeric polymer is blended with a reactive polymer having a functionality which is reactive with the polyamide. This blending occurs under conditions, such as in the presence of free radicals, which lead to the coupling of the elastomeric polymer and the reactive polymer and forms a block or graft copolymer. The graft or block copolymer is then blended with a polyamide. The composition is a multi-phase composition wherein the polyamide is generally a continuous phase, and the block or graft copolymer is present in the form of a particulate dispersed phase. The polyamide compositions have a wide range of improved properties such as good low temperature (e.g., minus 40.degree. C.) impact resistance and good high temperature heat deflection (e.g., 65.degree. C).
    • 提供了一种热塑性多相组合物,其是官能化嵌段或接枝共聚物和聚酰胺的熔融共混物。 共混物由聚合物制成。 也就是说,弹性体聚合物与具有与聚酰胺反应的官能团的反应性聚合物共混。 这种共混发生在诸如存在自由基的条件下,这导致弹性体聚合物和反应性聚合物的偶联,并形成嵌段或接枝共聚物。 然后将接枝或嵌段共聚物与聚酰胺共混。 组合物是多相组合物,其中聚酰胺通常是连续相,并且嵌段或接枝共聚物以颗粒分散相的形式存在。 聚酰胺组合物具有广泛的改进性能,例如良好的低温(例如-40℃)耐冲击性和良好的高温热偏转(例如65℃)。
