Abstract Poly(meth)acrylates are well-known commodity polymers widely used for coating applications due to easy production, low cost and interesting properties such as their relatively high thermal stability, resistance to breakage and transparency. Some of these properties can be improved by cross-linking, therefore an additional functionalization is necessary. Carbonate group allowed reaction with amines to generate a urethane linkage without the use of toxic and harmful isocyanates. We have synthesized (meth)acrylic copolymers functionalized with cyclic carbonates groups using butyl acrylate (BA), methyl methacrylate (MMA) and glycerol carbonate methacrylate (GCMA) as comonomers to obtain cross-linkable polymers. Different ratios of BA and MMA have been used in order to evaluate the effect on the thermo-mechanical properties. The cross-linking was performed with tris(2-aminoethyl)amine at 80 °C during 2 h and was quantitative. The cross-linked hydroxyurethane acrylate copolymers were fully characterized and were used as coatings on glass and steel. The ease of the application and curing process as well as the adhesion strength tests showed that these cross-linked copolymers are promising materials as coating on glass and steel.

甲基丙烯酸甘油碳酸酯：羟基氨基甲酸酯-丙烯酸酯涂料的交联剂

摘要 聚（甲基）丙烯酸酯是众所周知的商品聚合物，由于其易于生产、成本低和具有较高的热稳定性、抗破损性和透明度等特性而广泛用于涂料应用。这些特性中的一些可以通过交联来改善，因此需要额外的功能化。碳酸酯基团允许与胺反应生成氨基甲酸酯键，而无需使用有毒和有害的异氰酸酯。我们使用丙烯酸丁酯 (BA)、甲基丙烯酸甲酯 (MMA) 和甲基丙烯酸碳酸甘油酯 (GCMA) 作为共聚单体合成了用环状碳酸酯基团官能化的（甲基）丙烯酸共聚物，以获得可交联的聚合物。已使用不同比例的 BA 和 MMA 来评估对热机械性能的影响。在 80 °C 下用三（2-氨基乙基）胺在 2 小时内进行交联，并且是定量的。交联的羟基氨基甲酸酯丙烯酸酯共聚物被充分表征并被用作玻璃和钢上的涂层。应用和固化过程的简易性以及粘合强度测试表明，这些交联共聚物是作为玻璃和钢涂层的有前途的材料。
