The synthesis of well-defined block copolymers from one-pot monomer mixtures is particularly challenging when monomers are from the same class and show similar reactivity. Herein, an indium-based catalyst that shows comparable rates in the ring-opening homopolymerization of β-butyrolactone (β-BL) and ε-decalactone (ε-DL), demonstrates monomer-selective behavior in one-pot copolymerizations of β-BL and ε-DL. This provides simple and rapid access to well-defined di-, tri-, or tetra-block copolyesters from monomer mixtures. The sequence-controlled nature of these polymers was confirmed by kinetic analysis, 13C{1H} NMR spectroscopy, DSC, and TGA measurements.

使用铟催化剂从一锅法单体混合物中简单快速地制备 AB、BAB 和 ABAB 嵌段共聚酯

当单体来自同一类别并表现出相似的反应性时,从一锅法单体混合物合成明确定义的嵌段共聚物尤其具有挑战性。在此,一种铟基催化剂在 β -丁内酯 ( β -BL) 和 ε -癸内酯 ( ε -DL) 的开环均聚中表现出相当的速率,在β -BL一锅共聚表现出单体选择性行为和ε -DL。这提供了从单体混合物中简单快速地获得定义明确的二嵌段、三嵌段或四嵌段共聚酯。这些聚合物的序列控制性质已通过动力学分析、13 C{ 1H} NMR 光谱、DSC 和 TGA 测量。
