Abstract

The upcycling of polyethersulfone (), a high-performance polymer based on an aromatic-rich aryl-ether-based backbone, can advantageously yield both the starting comonomer bisphenol S () and valuable OLED derivatives, providing a complete atom valorization strategy for waste. Deprotonated selected amines have proved particularly efficient at depolymerizing at moderate temperatures (∼120 °C). The recycled monomer yields validate the back-to-monomer chemical recycling method for industrial compliance. The OLED derivatives afforded by the same simple process can easily be isolated, promoting an innovative upcycling strategy that transforms polymer into valuable chemicals, a highly relevant approach for mitigating the ever-growing plastic waste accumulation.

聚醚砜通过氨解升级回收为发光材料
聚醚砜(聚醚砜)是一种以芳香族芳醚为骨架的高性能聚合物,其升级回收有利于生成起始双酚S (BPS)共聚单体和有价值的OLED衍生物,为聚醚砜废弃物提供了完整的原子增值策略。在中等温度(~ 120°C)下,去质子化选定的胺对解聚PES特别有效。回收的单体产量验证了对单体化学回收方法的工业合规。通过同样简单的过程产生的OLED衍生物可以很容易地分离出来,并促进了一种创新的升级回收策略,使用聚合物到有价值的化学品,这是一种非常相关的方法,可以帮助缓解不断增长的塑料废物积累。
