A chemical vapor deposition (CVD) technique for the preparation of the conjugated polymer PPV , poly(phenylenevinylene), is presented. The thin films were prepared by CVD of a chlorine precursor polymer from a dichloro‐ p ‐xylene monomer followed by a thermal conversion step. The preparation and apparatus are detailed and results of UV‐vis and IR spectroscopy discussed. Spontaneous orientation of the polymer during growth is revealed, which suggests the possibility of fabricating chain‐oriented polymers by CVD.
