Abstract
Two-dimensional polycondensation of the poly(p-vinylphenol) (PVP) monolayer and formaldehyde in subphase or hexamethylenetetramine in subphase was studied by a surface balance. The reaction product was successfully built up on a Ge prism as a multilayer characterized by ellipsometry and ATR-IR spectra. Polycondensation in two dimensions actually occurred together with a tremendous increase in surface viscosity in the monolayer. The rate constants of reaction between the PVP monolayer and formaldehyde or hexamethylenetetramine for a constant area and also at constant surface pressure were determined and discussed.
