چکیده
Syntheses of organometallic initiators were conducted under a nitrogen atmosphere using standard Schlenk techniques. All reagents were of commercial grade and obtained from Sigma-Aldrich Co.. Solvents and the propionic acid used for the preparation of initiators were carefully dried and distilled under nitrogen atmosphere prior to use. TEMPO was sublimated and stored under nitrogen atmosphere. NMR spectra were acquired on a Varian Mercury 400 Spectrometer IR spectra were measured on Perkin-Elmer System 2000 FT-IR spectrophotometer. GC-MS analysis was performed on Agilent 6890N chromatograph coupled with Agilent 5973N MS detector.
