本工作描述了一个多阶段的连续流动聚合过程中使用的RAFT聚合方法的嵌段共聚物的合成。该工艺保留了RAFT方法的所有优点和多功能性，并适用于一系列单体组合，包括丙烯酸酯、丙烯酰胺和乙烯基单体。它导致聚合物的分子量在13500和34100 g mol-1之间，分散度通常在1.21和1.58之间。制备了不同的结构（包括亲水性和疏水性嵌段的组合），其可溶于一系列不同的溶剂，包括水性和有机介质。
This work describes a multi-stage continuous flow polymerisation process for the synthesis of block copolymers using the RAFT polymerization method. The process retains all the benefits and versatility of the RAFT method and has been adapted for a series of monomer combinations, including acrylates, acrylamides, and vinyl monomers. It resulted in polymers with molecular weights between 13500 and 34100 g mol–1, and dispersities typically between 1.21 and 1.58. Different architectures were prepared (including combinations of hydrophilic and hydrophobic blocks) which are soluble in a range of different solvents including aqueous and organic media.
