Novel copper catalyst containing a hydroxyl functional group: A facile strategy to block copolymers of vinyl monomer and ε-caprolactone via tandem reverse ATRP and ROP

Abstract

Reverse atom transfer radical polymerization (R-ATRP) and ring opening polymerization (ROP) are two representatives of the most promising living/controlled polymerization techniques. A facile and stable metal catalyst Cu(S(S=C)(N-CH3)CH2CH2OH)2 containing a hydroxyl group was firstly designed, targeting to prepare block copolymers of vinyl monomer and cyclic ester monomer via a combination of R-ATRP and ROP. The vinyl polymer chain end attached with hydroxyl functionality obtained from R-ATRP was directly used as macroinitiator to prepare block copolymers via ROP of ε-caprolactone. 1H NMR and GPC analyses as well as ROP chain-extension reaction confirmed that the vinyl polymers possessed the very high chain-end functionality, and the block copolymers of vinyl monomer and cyclic ester monomer has been successfully synthesized.
