Abstract
Dispersity (Đ) of polymers has a great effect on the properties of polymeric materials, and therefore how to control Đ is very important but still a huge challenge in polymer synthesis, especially for reversible-deactivation radical polymerization (RDRP) strategy. Herein, we successfully developed a novel strategy to adjust Đ of polymers by visible light-controlled reversible complexation mediated living radical polymerization (RCMP) and combination of single-electron transfer-degenerative chain transfer living radical polymerization (SET-DTLRP) at room temperature. In RCMP system, 2-iodo-2-methylpropionitrile (CP-I) and ethyl 2-iodo-2-phenylacetate (EIPA) were used as alkyl iodide initiators, by using methyl methacrylate (MMA) as the model monomer and n-butylacrylate (BA) as the end-cap** reagent to regulate Đ of polymers. Subsequently, we successfully prepared the block copolymer PMMA-b-PBA with adjustable Đ by reactivating the polymer end-chains via SET-DTLRP in the presence of copper wire, fully demonstrating that it is a promising strategy that can keep the “living” feature of polymers while regulating their molar mass dispersities easily.
