ABSTRACT

A completely metal-free and environmentally friendly strategy is demonstrated for the preparation of graft copolymers by combining photoinduced Atom Transfer Radical Polymerization (ATRP) and Ring Opening Polymerization (ROP). Polymerizations are simultaneously realized in a one-pot manner. For this purpose, bare vinyl monomers, vinyl monomers with hydroxyl functional groups, and lactone monomers were simultaneously polymerized under visible light using specific catalysts. While vinyl monomers construct the main chain, the lactone monomers were polymerized from the hydroxyl functions present at the side chain. Spectral and chromatographic analyses prove that the utilized strategy is successful in the preparation of graft copolymers controlled molecular weights and narrow distributions.

摘要

通过结合光诱导原子转移自由基聚合（ATRP）和开环聚合（ROP），证明了制备接枝共聚物的完全无金属且环保的策略。以一锅法同时实现聚合。为此目的，使用特定的催化剂在可见光下同时聚合裸乙烯基单体，具有羟基官能团的乙烯基单体和内酯单体。当乙烯基单体构成主链时，内酯单体从侧链上存在的羟基官能团聚合。光谱和色谱分析证明，所采用的策略在控制分子量和窄分布的接枝共聚物的制备中是成功的。
