Da. Loy et al., CHARACTERIZATION OF POLY(XYLYLENES) WITH SOLID-STATE C-13 NUCLEAR-MAGNETIC-RESONANCE SPECTROSCOPY, Macromolecules, 28(17), 1995, pp. 5799-5803
Poly(xylylenes) are an important class of thermoplastics that are read
ily prepared by thermolysis of [2.2]paracyclophane or xylene precursor
s to afford xylylene monomers that condense and polymerize on solid su
rfaces to give polymer films. As most poly(xylylenes) are insoluble du
e to a high degree of crystallinity, characterization by solid-state n
uclear magnetic resonance spectroscopic techniques is necessary. In th
is paper we describe the preparation of poly(xylylene) (P1), poly(2-et
hylxylylene) (P2), poly(2-chloroxylylene) (P3), poly(2,3-dichloroxylyl
ene) (P4), and oly(alpha,alpha,alpha',alpha'-tetrafluoroxylylene) (P5)
and their characterization using solid-state C-13 cross polarization
