Photon correlation spectroscopy (PCS) and IR spectroscopy methods were
used to try to verify polymerization of propargyl alcohol (PA) under
homogeneous and heterogeneous conditions. Results of PCS measurements
show that in systems where electrochemical measurements suggest strong
inhibitive effect no PA polymerization takes place in the bulk of sol
ution. The IR studies did not show any features that could be related
to a 3-D polymer film and therefore an adsorption model is favored.
