Abstract

It was demonstrated that Poly(p-Xylylene) (PPX) could be prepared from ,’-Bis(Alkoxy or Aryloxy) –p-Xylenes via chemical vapor decomposition (CVD)- method. This is one-step process and there are side products by the CVD-process. This effect depends both on the CVD- condition and the properties of the starting monomer. The structure and thermal behavior of the material were characterized by FTIR, UVvis spectroscopy, elemental analysis, wide-angle X-ray diffraction, DTA and DSC. It could be showed that the deposited PPX is semicrystalline and the melting process of PPX is characterized by the two crystalline phase transition and accompanied by decomposition. This research will open a new way to synthesize of PPX.
