阅读说明：本技术 丙烯酸聚酯树脂和含有其的水性涂料组合物 (Acrylic polyester resin and aqueous coating composition containing the same ) 是由 W·H·小雷特施 于 2019-06-20 设计创作，主要内容包括：描述了可通过将聚酯材料接枝到丙烯酸聚合物而获得的丙烯酸聚酯树脂。如权利要求1所示,可通过将(i)多元酸组分与(ii)多元醇组分聚合而获得聚酯材料,所述多元醇组分包括根据式(I)的二醇；其中R-1和R-2各自独立地表示氢基、低级烷基或具有6至12个碳原子的芳基,并且其中R-1或R-2中的至少一个为低级烷基或具有6至12个碳原子的芳基。R-3和R-4各自独立地表示低级烷基或具有6至12个碳原子的芳基。多元酸组分和/或多元醇组分中的至少一种包含可操作以将官能度赋予聚酯树脂的官能单体,使得可以经由使用所述官能度将聚酯材料接枝到丙烯酸聚合物上。还提供了一种包含所述丙烯酸聚酯树脂的水性涂料组合物,和一种含有用所述组合物涂覆的金属包装。(Acrylic polyester resins obtainable by grafting polyester materials to acrylic polymers are described. As shown in claim 1, the polyester material may be obtained by polymerizing (I) a polyacid component with (ii) a polyol component comprising a diol according to formula (I); wherein R is 1 And R 2 Each independently represents a hydrogen group, a lower alkyl group or an aryl group having 6 to 12 carbon atoms, and wherein R 1 Or R 2 In (1)At least one is a lower alkyl group or an aryl group having 6 to 12 carbon atoms. R 3 And R 4 Each independently represents a lower alkyl group or an aryl group having 6 to 12 carbon atoms. At least one of the polyacid component and/or the polyol component includes a functional monomer operable to impart functionality to the polyester resin such that the polyester material can be grafted onto the acrylic polymer via the use of the functionality. Also provided is an aqueous coating composition comprising the acrylic polyester resin, and a metal package coated with the composition.)
