阅读说明：本技术 丙烯酸聚酯树脂和含丙烯酸聚酯树脂的水性或粉末涂料组合物 (Acrylic polyester resin and aqueous or powder coating composition containing the same ) 是由 W·H·小雷特施 N·F·马斯特斯 于 2019-07-25 设计创作，主要内容包括：描述了一种丙烯酸聚酯树脂,其可通过将丙烯酸聚合物与聚酯材料接枝来获得。所述聚酯材料可通过使(i)多元酸组分与(ii)多元醇组分聚合来获得,其中所述多元酸组分和所述多元醇组分中的一种或两种包含Tg增强单体。所述多元酸组分或所述多元醇组分之一包括官能单体,所述官能单体可操作以将官能性赋予所述聚酯树脂,使得丙烯酸聚合物可以通过使用所述官能性与所述聚酯材料接枝。还提供了一种包括所述丙烯酸聚酯树脂的水性或粉末涂料组合物以及一种含有涂覆有所述组合物的金属包装。(An acrylic polyester resin is described, which is obtainable by grafting an acrylic polymer with a polyester material. The polyester material is obtainable by polymerizing (i) a polyacid component and (ii) a polyol component, wherein one or both of the polyacid component and the polyol component comprise a Tg enhancing monomer. One of the polyacid component or the polyol component includes a functional monomer operable to impart functionality to the polyester resin such that an acrylic polymer may be grafted with the polyester material through the use of the functionality. Also provided are an aqueous or powder coating composition comprising the acrylic polyester resin and a metal package containing a coating coated with the composition.)
