摘要：
The behavior of monomolecular and thin films of poly(dipropylsiloxane) spread on the subphases of ethylene glycol and its mixtures with water was studied by measuring surface pressure as a function of specific surface area per repeating monomer unit. It was shown that poly(dipropylsiloxane) forms stable monolayers on ethylene glycol. The mechanism describing the formation of layers on the alcohol subphase was advanced. For a series of polymers, poly(dimethylsiloxane)-poly(diethylsiloxane)- poly(dipropylsiloxane), the structure and properties of monomolecular films were compared.
