摘要: The effects of acidic components and asphaltenes on the dilational rheological properties hydrophobically modified polyacrylamide (APP5) have been measured as a function time, frequency, bulk concentration, interfacial pressure by means drop shape analysis method. It is established that play an important role APP5/crude oil component mixture at water–kerosene interface. With addition components, modulus not only increases with time but also higher low concentrations runs through maximum lower concentration compared to pure APP5. Also, phase angle APP5/acidic results indicate appearance more elastic films because mixed adsorption APP5 molecules. does influence high concentrations. However...
