Synthesis of an Amphiphilic Brush Copolymer by a Highly Efficient "Grafting onto" Approach via CO2 Chemistry

A novel and robust route for the synthesis of a new amphiphilic brush copolymer, poly(glycidyl methacrylate)‐graft‐polyethylene glycol (PGMA‐g‐PEG), with high grafting densities of 97%–98% through a “grafting onto” method via carbon dioxide chemistry is reported. PGMA‐g‐PEG can self‐assemble and for...

Description
Summary:A novel and robust route for the synthesis of a new amphiphilic brush copolymer, poly(glycidyl methacrylate)‐graft‐polyethylene glycol (PGMA‐g‐PEG), with high grafting densities of 97%–98% through a “grafting onto” method via carbon dioxide chemistry is reported. PGMA‐g‐PEG can self‐assemble and form stable spherical core–shell micelles in aqueous solution. Besides, the obtained PGMA‐g‐PEG polymer contains hydroxyurethane structures as the junction sites between the PGMA backbone and PEG side chain, which can be used for further modification. The synthesis of a new amphiphilic brush copolymer through a “grafting onto” method via carbon dioxide chemistry is described. The polymer shows high grafting densities of 97%–98% and a hydroxyurethane structure as the junction site between the poly(glycidyl methacrylate) backbone and side polyethylene glycol chain
