The vast majority of commodity materials are obtained from petrochemical feedstocks. These resources will plausibly be depleted within the next 100 years, and the peak in global oil production is estimated to occur within the next few decades. In this regard, biomass represents an abundant carbon-neutral renewable resource for the production of polymers. Here we report a new strategy, based on tandem catalysis, to obtain renewable materials. Commercially available complexes are found to be efficient catalysts for alternating polyesters from the cyclization of dicarboxylic acids followed by alternating copolymerization of the resulting anhydrides with epoxides. This operationally simple method is an attractive strategy for the production of new biodegradable polyesters.
绝大多数商品材料都是从石化原料中获得的。这些资源很可能在未来 100 年内耗尽，而全球石油产量的峰值预计将在未来几十年内出现。在这方面，生物质代表了一种丰富的碳中和可再生资源，可用于生产聚合物。在这里，我们报告了一种基于串联催化的新策略，以获得可再生材料。商业上可用的配合物被发现是有效的催化剂，可用于通过二酸的环化形成交替聚酯，然后用所得的酸酐与环氧化物进行交替共聚。这种操作简单的方法是生产新型可生物降解聚酯的一种有吸引力的策略。
