New Monomers for Chemical Vapor Deposition Polymerization of Poly (p-Xylylene)

Nguyen Duc Nghia, Ngo Trinh Tung, Jung Il Jin

Tóm tắt

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.
