摘要：

The effects of fluoroalcohol solvents on the stereochemistry of methyl methacrylates (MMA), ethyl methacrylates (EMA), and tert-butyl methacrylates polymerizations were investigated. The polymerization of MMA in perfluoro-tert-butyl alcohol and EMA in hexafluoro-2-methyl-2-propanol at -40 °C resulted in the highest syndiotactic content for poly(MMA) and poly(EMA).
