Abstract

The overlap concentration C* of DMAM-TBAM associative copolymer (the DMAM and TBAM are abbreviations of N, N-dimethylacrylamide and t-butylacrylamide) with different hydrophobic monomer ratios has been studied using viscosity and refractive index measurements at various temperatures (298.15, 303.15 and 308.15) K. The obtained overlap concentration using viscosimetry method is lower respect to what obtained from refractometry. The effect of the temperature as well as molecular weight and hydrophobic monomer ratio on the overlap concentration was investigated. The experimentally C* values compared with those calculated to the Huggins, Rao and Fuoss equations.
