change the degradation profile of the polymer and the identity of the resulting degradation products. For instance, the large difference in degradation rates between hemi‐aminal ether and ether‐based polymers enabled the sequential degradation of a block copolymer. Furthermore, we exploited the generation of furan‐based degradation products, from an acetal‐based polymer, to achieve the release of covalently
衍生自D-木糖的Enyne单体进行了活性级联聚合,以制备具有开环糖和可降解键合的新聚合物,并在骨架的每个重复单元中引入了可降解键。聚合反应得到很好的控制,并具有活泼的特性,从而可以制备分子量分布窄的高分子量聚合物和嵌段共聚物。通过调节对酸敏感的键的类型(半氨基醚,乙缩醛或醚官能团),我们可以改变聚合物的降解曲线和所得降解产物的身份。例如,半氨基醚和基于醚的聚合物之间的降解速率差异很大,可以使嵌段共聚物依次降解。此外,我们还开发了基于呋喃的降解产物,
