Unimolecular ligand–initiator dual functional systems (ULIS) for low copper ATRP of vinyl monomers including acrylic/methacrylic acids

Abstract

A novel approach for ATRP has been developed which enables the polymerization of vinyl monomers including those bearing carboxylic acid groups such as acrylic/methacrylic acid in the free acid form with ppm amounts of copper. The quantity of copper used in the polymerization is comparable to those left in purified polymers obtained by a conventional ATRP process.

Dual hydrophilic and salt responsive schizophrenic block copolymers – synthesis and study of self-assembly behavior

“…Developments in radical polymerization such as atom transfer radical polymerization (ATRP) [25][26][27][28] and reversible additionfragmentation chain transfer (RAFT) polymerization [29][30][31][32] allow the facile formation of block copolymers. In the recent past, we have reported PEG derived macroinitiators for synthesizing block copolymers under ATRP conditions.…”
