Powder coating resins and coatings made using the powder coating resins are described. The powder coating resins are based on the use of C12 to C23 diesters. The C12 to C23 diesters are reacted with areactant having an alcohol functionality and an amine functionality to form an intermediate polyol, followed by reaction with a diacid to a carboxylic acid terminated polymer having ester and amide functionality. 描述了粉末涂料树脂和使用该粉末涂料树脂制备的涂料。该粉末涂料树脂基于C12至C23二酯的使用。使C12至C23二酯与具有醇官能团和胺官能团的反应物反应，以形成中间体多元醇，然后与二酸反应成具有酯官能团和酰胺官能团的羧酸封端的聚合物。
