Well-Defined C6o End-Capped Polymers by Controlled Radical Polymerization

Well-Defined Qo End-Capped Polymers by Controlled Radical Polymerization 

To synthesize Coo-containing polymers with narrow molar mass distribution, the preformed polymer that is conjugated to C o must be prepared by hving polymerization. However, there have been few reports on the synthesis of weU-defined Ca,-containing polymers using living polymerization because of the strin- 

Recently, we have synthesized a series of well-defined stimuli responsive, water-soluble, fuUerene-containing polymers using ATRP. A well-defined alkali-soluble Co) end-capped poly(methacryhc acid) was synthesized by ATRP using group protecting chemistry [82]. A well-defined, stable Gl-terminated poly(tert-butyl methacrylate) (PtBMA) was synthesized using p-toluenesulfonic acid (p-TSA) as an initiator in the presence of CuCl/HMTETA catalyst complex at 90 °C. The Cl-terminated PtBMA was further used to perform in the presence of excess of Cso 

In addition, Cai et al. have proposed a reverse atom transfer radical polymerization (RATRP) approach to prepare end-functionalized PMMA with and C70 [88]. The Cl-terminated PMMA-Cl as reaction precursor was synthesized through RATRP in the presence of an AlBN/FeCl3/PPh3 initiating system in solution and in bulk, respectively. The polymer was then functionalized with C or C70 by ATRA using Cu/CuBr/bipy or EeCh/bipy as catalyst to form well-defined PMMA-Cgo.
