    • An improved process for preparing a vinyl oxazoline drying oil ester by reacting drying oil fatty acids with tris(hydroxy methyl) amino methane to form an intermediate which is further reacted at about 175.degree.-190.degree. C. with a formaldehyde/alcohol solution to form the vinyl oxazoline drying oil ester; the improvement used with this process is the use of at least 3 moles of formaldehyde to one mole of intermediate and about 1-5% by weight, based on the weight of the intermediate, of methanol and adding after the reaction with formaldehyde about 5-25% by weight, based on the weight of the ester solution, of an alcohol, a ketone or a mixture of an alcohol and a ketone; polymers of this ester and coating compositions of these polymers are also disclosed.
    • 一种通过干燥油脂肪酸与三(羟基甲基)氨基甲烷反应制备乙烯基恶唑啉干燥油酯的改进方法,以形成中间体,其进一步在约175-190℃下与甲醛/醇溶液反应形成 乙烯基恶唑啉干油酯; 使用该方法的改进是使用至少3摩尔甲醛至1摩尔中间体和约1-5重量%(基于中间体的甲醇重量),并在与甲醛反应后加入约5- 25重量%,基于酯溶液的重量,醇,酮或醇和酮的混合物; 还公开了该酯的聚合物和这些聚合物的涂料组合物。
