A new class of bio‐based fully degradable block polyesters are pressure‐sensitive adhesives. Bio‐derived monomers are efficiently polymerized to make block polyesters with controlled compositions. They show moderate to high peel adhesions (4–13 N cm⁻¹) and controllable storage and loss moduli, and they are removed by adhesive failure. Their properties compare favorably with commercial adhesives or bio‐based polyester formulations but without the need for tackifier or additives.

生物衍生的可降解嵌段聚酯压敏粘合剂。

一类新型生物基完全可降解嵌段聚酯是压敏粘合剂。生物衍生单体可有效聚合，制造成分受控的嵌段聚酯。它们表现出中等到高的剥离粘合力（4-13 N cm ^-1）和可控的储能模量和损耗模量，并且它们会因粘合失效而被去除。它们的性能优于商业粘合剂或生物基聚酯配方，但不需要增粘剂或添加剂。
