Poly(eugenol-co-methylmethacrylate)/polypropylene blends were successfully prepared using methyl methacrylate (MMA), eugenol (Eg) and polypropylene (PP). First, poly(eugenol-co-methylmethacrylate) (poly(Eg-co-MMA)) was synthesized by photopolymerizaiton in one step at ambient temperature and without solvent. Benzophenone and triethylamine were used as photoinitiator and hydrogen donor, respectively. The second stage is the blending approach between polypropylene and poly(Eg-co-MMA) copolymer. The anti-bacterial test was carried out using the agar well diffusion. Escherichia coli, Staphylococcus aureus bacterial species were tested using Clinical and Laboratory Standards Institute (CLSI) Disk-Diffusion method in antibacterial analysis. As a result of these studies, the blend polymers (PEgMMA1:1)30-PP and (PEgMMA1:1)50-PP showed activity against E. coli Gram-negative bacteria. Zone diameters are 7 ± 0.00 mm and 5.25 ± 0.25 mm for (PEgMMA1:1)30-PP and (PEgMMA1:1)50-PP, respectively. No activity has been observed against S. aureus bacteria. In antimicrobial tests, it was determined that the polymers did not show a high antibacterial property as expected. Structural characterization and thermal properties of the synthesized terpolymers were performed by FTIR (Fourier-transform infrared spectroscopy), 1H NMR (nuclear magnetic resonance spectroscopy), TG-DTG (thermogravimetry-derivative thermogravimetry). SEM (scanning electron microscope) was used for surface analysis. The thermal stability of the synthesized blend polymers was higher than their homopolymers. Structural characterizations and surface analyzes support the successful performance of the synthesis.

通过创新途径制备聚(丁子香酚-共-甲基丙烯酸甲酯)/聚丙烯共混物:结构和热表征

聚(eugenol--methylmethacrylate)/使用甲基丙烯酸甲酯(MMA),丁子香酚(例如)和聚丙烯(PP)成功地制备聚丙烯的共混物。首先,聚(丁子香酚-co-甲基丙烯酸甲酯)(聚(Eg- co- MMA))在环境温度和无溶剂下通过一步光聚合合成。二苯酮和三乙胺分别用作光引发剂和氢供体。第二阶段是聚丙烯和聚(Eg- co- MMA)共聚物之间的共混方法。使用琼脂孔扩散进行抗菌试验。大肠杆菌金黄色葡萄球菌在抗菌分析中使用临床和实验室标准协会 (CLSI) 圆盘扩散法测试细菌种类。作为这些研究的结果,共混聚合物(PEgMMA 1:1 ) 30 -PP和(PEgMMA 1:1 ) 50 -PP显示出抗大肠杆菌革兰氏阴性菌的活性。(PEgMMA1:1) 30 -PP 和 (PEgMMA1:1) 50 -PP 的区域直径分别为 7 ± 0.00 mm 和 5.25 ± 0.25 mm 。未观察到针对金黄色葡萄球菌的活性细菌。在抗菌测试中,确定聚合物没有表现出预期的高抗菌性能。合成的三元共聚物的结构表征和热性能通过 FTIR(傅里叶变换红外光谱)、1 H NMR(核磁共振光谱)、TG-DTG(热重-导数热重)进行。SEM(扫描电子显微镜)用于表面分析。合成的共混聚合物的热稳定性高于它们的均聚物。结构表征和表面分析支持合成的成功性能。
