Abstract

Abstract: Atom transfer radical polymerization (ATRP) performed in ab initio emulsion provides access to well-defined polymers in a low-cost, eco-friendly environment. Herein, photoinduced ab initio emulsion ATRP of various (meth)acrylate monomers is reported. The polymerization rate increased with the solubility of the monomer in water. Well-controlled (co)polymerizations were achieved under violet light and low catalyst loading, even in an open-to-air system through enzymatic degassing. Graphical abstract: Image 1 Highlights: PhotoATRP conducted in ab initio emulsion. Rate of polymerization correlated to monomer hydrophobicity. Enzymatic deoxygenation enabled simplified reaction setup at low cost. Highly hydrophobic monomers shuttled by more hydrophilic monomers to form copolymers. Facile copolymers preparation by feeding the second monomer in situ
