Characterization of polyxylylenes with solid state {sup 13}C nuclear magnetic resonance spectroscopy
- Sandia National Labs., Albuquerque, NM (United States); and others
Polyxylylenes are an important class of thermoplastics that are readily prepared by thermolysis of [2.2]paracyclophane or xylene precursors to afford xylylene monomers that condense and polymerize on solid surfaces to give polymer films. As most polyxylylenes are insoluble due to a high degree of crystallinity, characterization by solid state nuclear magnetic resonance spectroscopic techniques is necessary. In this paper we describe the preparation of polyxylylene, poly-2-ethylxylylene, poly-2-chloroxylylene, poly-2, 3-dichloroxylylene, and poly({alpha}, {alpha}, {alpha}{prime}, {alpha}{prime}-tetrafluoroxylylene) and their characterization using solid state {sup 13}C Cross Polarization Magic Angle Spinning Nuclear Magnetic Resonance (CP MAS NMR) spectroscopy.
