This study presents the preparation and the thermo-mechanical characteristics of polymeric blends based on di(meth)acrylates monomers. Bisphenol A glycerolate diacrylate (BPA.GDA) or ethylene glycol dimethacrylate (EGDMA) were used as crosslinking monomers. Methyl methacrylate (MMA) was used as an active solvent in both copolymerization approaches. Commercial polycarbonate (PC) was used as a modifying soluble additive. The preparation of blends and method of polymerization by using UV initiator (Irqacure 651) was proposed. Two parallel sets of MMA-based materials were obtained. The first included more harmless linear hydrocarbons (EGDMA + MMA), whereas the second included the usually used aromatic copolymers (BPA.GDA + MMA). The influence of different amounts of PC on the physicochemical properties was discussed in detail. Chemical structures of the copolymers were confirmed by attenuated total reflection-Fourier transform infrared (ATR/FT-IR) spectroscopy. Thermo-mechanical properties of the synthesized materials were investigated by means of differential scanning calorimetry (DSC), thermogravimetric (TG/DTG) analyses, and dynamic mechanical analysis (DMA). The hardness of the obtained materials was also tested. In order to evaluate the surface of the materials, their images were obtained with the use of atomic force microscopy (AFM).
本研究介绍了基于二（甲基）丙烯酸酯单体的聚合物共混物的制备及其热机械特性。双酚A甘油酸二丙烯酸酯（BPA.GDA）或乙二醇二甲基丙烯酸酯（EGDMA）用作交联单体。甲基丙烯酸甲酯（MMA）在两种共聚方法中均用作活性溶剂。商用聚碳酸酯（PC）用作改性可溶性添加剂。提出了使用紫外线引发剂（Irgacure 651）制备共混物和聚合方法。获得了两组平行的基于MMA的材料。第一组包含更多无害的线性烃（EGDMA + MMA），而第二组包含常用的芳族共聚物（BPA.GDA + MMA）。详细讨论了不同量的PC对物理化学性质的影响。通过衰减全反射傅里叶变换红外光谱（ATR/FT-IR）确认了共聚物的化学结构。通过差示扫描量热法（DSC）、热重分析（TG/DTG）和动态力学分析（DMA）研究了合成材料的热机械性能。还测试了所得材料的硬度。为了评估材料的表面，使用原子力显微镜（AFM）获得了它们的图像。
