POLYSILOXANE LANGMUIR FILMS - LINEAR POLY SILOXANES

We behavior of monomolecular and thin films of various linear polysilo xanes such as polydimethyl-, polydiethyl-, polydipropyl-, and polyalky lmethylsiloxanes were investigated using the measurements of the depen dence of surface pressure on the reduced area per monomer unit of poly mer. The influence of molecular mass, temperature, and pH of water on the formation of thin and monomolecular Langmuir films was studied. Po lysiloxanes with alkyl substituents, which are longer than one methyl group, form thin films rather than the monomolecular layers.
