The synthesis and characterization of linear poly(ether 1,2-glycerol carbonate)s derivatized with pendant butyl, octyl, or stearyl tethers are reported. The polymers are obtained via the ring-opening copolymerization of butyl, octyl, or stearic glycidyl ethers with carbon dioxide using the [-SalcyCoDNP] catalyst bearing a quaternary ammonium salt. Synthesized polymers were characterized by H and C NMR spectroscopy, FT-IR, gel permeation chromatography (GPC), differential scanning calorimetry (DSC), and rheometry. Polymers with controlled molecular weights in the range of 8970-31 900 g/mol were obtained with low polydispersities between 1.1 and 1.4. Thermal properties of the materials confirm amorphous structures of the polymers with butyl and octyl chains, with glass transition temperatures of -24 and -34 °C, respectively. The stearyl tether polymer exhibited a melting point of 55 °C. Additionally, the potential of poly(butyl ether 1,2-glycerol carbonate) as a thermally stable solid polymer electrolyte was investigated, and it exhibits temperature-dependent conductivity with values comparable to those of optimized PEO-based electrolytes.
本文报道了带有丁基、辛基或硬脂基侧链的线性聚（1,2 - 甘油碳酸酯醚）的合成与表征。这些聚合物是通过丁基、辛基或硬脂基缩水甘油醚与二氧化碳在带有季铵盐的[-SalcyCoDNP]催化剂作用下进行开环共聚反应制得的。合成的聚合物通过氢核磁共振（H NMR）、碳核磁共振（C NMR）光谱、傅里叶变换红外光谱（FT - IR）、凝胶渗透色谱（GPC）、差示扫描量热法（DSC）和流变学进行表征。得到了分子量在8970 - 31900 g/mol范围内且多分散性较低（在1.1至1.4之间）的聚合物。材料的热性能证实了带有丁基和辛基链的聚合物具有非晶结构，其玻璃化转变温度分别为 - 24℃和 - 34℃。硬脂基侧链聚合物的熔点为55℃。此外，还研究了聚（丁基醚1,2 - 甘油碳酸酯）作为热稳定固体聚合物电解质的潜力，其表现出与温度相关的电导率，数值与优化的聚环氧乙烷（PEO）基电解质相当。
