There is growing interest in using photoinitiator‐free systems in coating applications such as inkjet‐printing, because residual photoinitiator can alter the properties of the resulting polymer. Bismaleimides (BMI) offer the opportunity to polymerize acrylates without the addition of photoinitiators, as this class of molecules can serve both as polymerizable monomer and as photoinitiator together with electron donor systems, like vinyl ether monomers or acrylates. The UV‐induced copolymerization of a low‐molecular‐weight BMI with various acrylate monomers and oligomers without any photoinitiator was characterized. The BMI‐acrylate systems show comparable polymerization speeds to widely used acrylic systems with photoinitiator. Superior thermal stability as well as thermomechanical properties are achieved by enhancing acrylics with BMI. Such photoinitiator‐free systems lend themselves to be used for low‐migration coatings as well as for high‐temperature applications. Here, a characterization of selected BMI‐acrylate mixtures regarding their photocuring kinetics and their application as inks for inkjet printing is shown. © 2019 The Authors.

丙烯酸酯-双马来酰亚胺混合物的无光引发剂光聚合及其在喷墨印刷中的应用

在涂料应用（如喷墨印刷）中使用无光引发剂的系统引起了越来越多的兴趣，因为残留的光引发剂会改变所得聚合物的性能。双马来酰亚胺（BMI）提供了在不添加光引发剂的情况下聚合丙烯酸酯的机会，因为这类分子既可以用作可聚合单体，也可以与电子给体体系（如乙烯基醚单体或丙烯酸酯）一起用作光引发剂。表征了低分子量BMI与各种丙烯酸酯单体和低聚物的光诱导共聚反应，而没有任何光引发剂。BMI-丙烯酸酯体系显示出与广泛使用的带有光引发剂的丙烯酸体系相当的聚合速度。通过使用BMI增强丙烯酸树脂，可以获得出色的热稳定性和热机械性能。这种无光引发剂的系统适用于低迁移率涂料以及高温应用。此处显示了所选BMI-丙烯酸酯混合物的光固化动力学特性及其在喷墨印刷中的应用。©2019作者。由Wiley Periodicals，Inc.出版的《应用聚合物科学杂志》。Polym。科学 2019，136，47789。
