We introduce a novel sulfur-containing polyester derivative based on a renewable monomer bearing secondary disulfide groups. Specifically, we demonstrate that this secondary disulfide moiety, placed in each repeating unit within the polymer, enables the introduction of high sulfur content by virtue of an organocatalytically triggered sulfur exchange reaction using elemental sulfur, thereby facilitating the synthesis of sustainable aliphatic polyesters with tailored functional properties.

元素硫在合成高硫含量的生物基脂族聚酯中的潜在潜力†

我们引入一种基于带有仲二硫键基团的可再生单体的新型含硫聚酯衍生物。具体而言，我们证明了该仲二硫键部分（放置在聚合物中的每个重复单元中）能够通过使用元素硫进行有机催化触发的硫交换反应来引入高硫含量，从而促进具有定制功能的可持续脂肪族聚酯的合成特性。
