Viscous properties of the copolymers in different solvents were studied. The unusual changes of viscosity in NaCl salt solution and alcohol/water solu ...展开
tion are due to macromonomer blocks containing both hydrophilic and hydrophobic groups. The study of surface activity and micellar properties of the cop1ymers testify, that micellar solubilizing effect is related with the type of macromonomer. Toluene is solrubilized in micellar core, and it is the length of hydrophilic and hydrophobic chain segment of macromonmers that influence the phase diagram of copolymner aqueous solution/toluene/propanol microemulsions. The study of adsorption and orientation of copolymers at the surface of aqueous solutions shows that hyvdrophilic and hydrophobic groups of copolymers are enriched at the surface, part of CMC chain segments are also drawn to the surface. At solid/liquid interface of SiO_2/H_2 O monolayer adsorption structure is formed by CMC-AEO9 system, while multilayer adsorption structure is formed by CMC-AEO2O system. 收起
