A controlled polymerization using activated acrylate monomers via ARGET-ATRP is developed with a tris[(4-dimethylamino pyridyl)methyl]amine ligand to address issues with weaker ligands and monomers that can undergo postpolymerization functionalization. This catalyst system enables the polymerization of N-acryloxy succinimide, fluorinated monomers, and isocyanato ethyl acrylate under controlled homogeneous conditions, ensuring linear molecular-weight growth and low polydispersity. Two block copolymerization strategies produce amphiphilic copolymers with narrow molecular-weight distributions and customizable compositions, allowing for various postpolymerization functionalizations.

使用 TPMANMe2 配体对反应性丙烯酸酯进行银介导的 ARGET-ATRP：受控共聚的通用策略

使用 ARGET-ATRP 使用活化丙烯酸酯单体与三[（4-二甲基氨基吡啶基）甲基]胺配体开发了一种受控聚合，以解决可能进行后聚合官能化的较弱配体和单体的问题。该催化剂系统能够在受控的均相条件下实现 N-丙烯氧基琥珀酰亚胺、氟化单体和丙烯酸异氰酸乙酯的聚合，确保线性分子量生长和低多分散性。两种嵌段共聚策略可产生具有窄分子量分布和可定制成分的两亲性共聚物，可实现各种后聚合官能团化。
