Synthesis and characterization of perfluoroalkyl-terminated polymers
- Univ. of North Carolina, Chapel Hill, NC (United States)
The focus of the authors` research was the synthesis of heterophase block copolymers composed of fluorinated segments with conventional polymers. This was accomplished in a facile, unique one pot synthesis via termination of a living polymeric carbanion with a perfluorinated chlorosilane. This synthetic methodology has been successful applied to styrenics, dienes, and siloxanes. Excellent control of the molar mass, molar mass distribution, and functionality was verified using conventional characterization technique such as gel premeation chromatography (GPC), NMR, and elemental analysis. The authors have also shown the utility of time-of-flight secondary ion mass spectrometry (TOF-SIMS) for characterization not only of absolute molar masses and molar mass distributions, but also for the determination of the extent of functionalization.
