## Abstract The thermal behavior of a waterโsoluble associating polymer system, hydrophobically modified alkaliโsoluble emulsion (HASE) polymer, was investigated. This polymer contains a methacrylic acidโethyl acrylate copolymer backbone with 1 mol % of pendant hydrophobic groups grafted to it. The
## Abstract Hydrophobically modified polyacrylamide hydrogels were prepared by polymerizing acrylamide, using __n__โbutyl acrylate and 2โethyl hexyl acrylate as comonomers and dimethyl formamide as a solvent. We report here for the first time that the Alfred Qโe reactivity ratios are matching with
The rheological properties of hydrophobic alkali-soluble associative polymers (HASE) were studied using controlled rate (Mettler LS40) and controlled stress (TA CSL 500) rheometers. The effects of pH and polymer concentrations on the rheological properties of three HASE model polymer systems (i.e.,
