一类新的生物基完全可降解嵌段聚酯是压敏粘合剂。生物衍生的单体被有效地聚合以制造具有受控组成的嵌段聚酯。它们表现出中等到高的剥离粘附力(4-13 N cm−1)和可控的存储和损耗模量,并且它们通过粘合剂失效而被移除。 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。使用可再生单体的混合物和使用单一催化剂的一锅合成方法制备定义明确的生物基三嵌段聚酯。这些材料是压敏粘合剂,在酸性条件下容易降解。
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. Well‐defined bio‐based triblock polyesters were prepared using a mixture of renewable monomers and a one‐pot synthetic method with a single catalyst. These materials are pressure‐sensitive adhesives and are easily degraded under acidic conditions.
