We report the rapid, one-pot synthesis of functional polycarbonates derived from renewable alcohols (i.e., glucose tetraacetate, acetyl isosorbide, lauryl alcohol, and ethanol) and a cyclic carbonate bearing an imidazolecarboxylate. This tandem functionalization/ring-opening polymerization strategy can be performed on multigram scale and eliminates the need for rigorous purification and specialized equipment. A wide range of glass transition temperatures () was accessible from these renewable pendant groups (>75 °C window). We also synthesized several statistical copolycarbonates to show the thermal properties can be tailored with this tandem method. Additionally, we demonstrate a circular polymer economy via chemical recycling to a cyclic carbonate precursor. This work may facilitate development of sustainable polycarbonates with tailored properties that work toward eliminating plastic waste streams.
我们报道了一种快速的一锅法合成功能性聚碳酸酯的方法，该聚碳酸酯由可再生醇（即葡萄糖四乙酸酯、乙酰异山梨醇、月桂醇和乙醇）和带有咪唑羧酸盐的环状碳酸酯衍生而来。这种串联功能化/开环聚合策略可以在多克规模上进行，无需严格的纯化和专门的设备。通过这些可再生侧基可以获得广泛的玻璃化转变温度（）（>75°C范围）。我们还合成了几种统计共聚物聚碳酸酯，以表明可以通过这种串联方法调整热性能。此外，我们通过化学循环至环状碳酸酯前体展示了循环聚合物经济。这项工作可能有助于开发具有定制性能的可持续聚碳酸酯，以致力于消除塑料废物流。
