Heterometallic cooperativity is gaining momentum in cyclic ester ring-opening polymerisation, yet remains surprisingly underexplored in their block copolymerisations. Here, we report the first homogeneous heterometallic “ate” catalysts for poly(ε-caprolactone)–poly(lactic acid) block copolymers, showcasing the substantial differences in the polymer structures observed upon exchanging Zn for Mg or Ca.

协同异金属催化剂:平衡 PCL-嵌段-PLA 共聚物合成中的活性和控制

异金属协同性在环酯开环聚合中正在获得动力,但令人惊讶的是,在嵌段共聚中,异金属协同性仍然未被充分开发。在这里,我们报道了第一个用于聚(ε-己内酯)-聚(乳酸)嵌段共聚物的均相异金属“ate”催化剂,展示了将 Zn 交换为 Mg 或 Ca 时观察到的聚合物结构的显着差异。
