Four linear dimers of 4-(hexyloxy)phenylacetylene I have been synthesi
zed and thermally polymerized under the same conditions which were use
d for I. The polymerization of monomer and linear dimer mixtures was a
lso studied. The reaction products were analysed by chromatography, sp
ectroscopy and spectrometry techniques. The experimental results led u
s to conclude that the linear dimers are not reaction intermediates of
the thermal polymerization of I. (C) 1997 Elsevier Science Ltd.
