Effect of Ligand Spacer on Silica Gel Supported Atom Transfer Radical Polymerization of Methyl Methacrylate
Abstract
Silica gels grafted with tetraethyldiethylenetriamine (TEDETA) and di(2-picolyl)amine (DiPA) via poly(ethylene glycol) (PEG) spacers of different chain lengths were synthesized and used as CuBr support for the atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA). The spacer length strongly affected the polymerization rate and polymer molecular weight control. Catalyzed by CuBr immobilized on the silica gel, the MMA …
