  摘要：

  通过光谱方法研究了对氨基二苯基二胺的电子给体与马来酸酐的电子受体之间的相互作用形成的新的电荷转移络合物和酰胺化反应。酰胺化反应是由马来酸酐和对氨基二苯基二胺分子的质子和电荷转移引起的。Benesi-Hildebrand方程已被用于通过Uv-Vis光谱法确定配合物的形成常数摩尔消光系数和标准的Gibbs自由能。为了启发和强调所考虑分子的电子和光谱性质，已经对结构MA，PADPA和CTC进行了理论计算。还通过IR，NMR和HRMS光谱鉴定了电荷转移络合物和酰胺化反应机理。通过循环伏安法，热重分析，XRD和SEM表征了马来酸酐...对氨基二苯基二胺配合物的性质。该复合物的微带固体显示出比对氨基二苯基二胺更高的热稳定性。

  The improved high solids coating composition contains at least 50% by weight of a binder of film-forming constituents in which the constituents are of (A) an acrylic polymer that has a number average molecular weight of about 500-10,000 and preferably 500-4,500, a hydroxyl content of at least 2% by weight, a glass transition temperature of about -20°C to +20°C and contains about 2-10% by weight of a chain transfer agent, and is of an alkyl methacrylate, a hydroxyalkyl acrylate or a hydroxyalkyl methacrylate, and optionally, an alkyl acrylate or styrene and (B) an alkylated melamine formaldehyde cross-linking agent; the improvement used with this composition is the addition of select ultraviolet light stabilizers and optionally, antioxidants. The composition is particularly useful for clear cost/color coat exterior finishes for automobiles, trucks and airplanes.
