Phase Behavior of Cationic Hydroxyethyl Cellulose−Sodium Dodecyl Sulfate Mixtures:  Effects of Molecular Weight and Ethylene Oxide Side Chain Length of Polymers

Phase Behavior of Cationic Hydroxyethyl Cellulose−Sodium Dodecyl Sulfate Mixtures:  Effects of Molecular Weight and Ethylene Oxide Side Chain Length of Polymers

Novel cationic hydroxyethyl cellulose (HEC) polymers with different molecular weights (1.1 × 105 to 1.7 × 106 g/mol) and ethylene oxide (EO) side chain lengths (1.5−2.9 EO units) were mixed with sodium dodecyl sulfate (SDS) in aqueous solutions. The phase diagrams of cationic HEC−SDS complexes were...

Zusammenfassung:Novel cationic hydroxyethyl cellulose (HEC) polymers with different molecular weights (1.1 × 105 to 1.7 × 106 g/mol) and ethylene oxide (EO) side chain lengths (1.5−2.9 EO units) were mixed with sodium dodecyl sulfate (SDS) in aqueous solutions. The phase diagrams of cationic HEC−SDS complexes were determined in the dilute polymer concentration regime (
