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.,
Adsorption of polycation as well as the modification with oppositely charged polyelectrolytes is a useful tool for surface modification. As shown previously, a strong enhancement of the attainable specific cationic surface charge was observed, e.g., with poly(diallyl-dimethylammonium chloride) (PDAD
Copolymers of acrylic acid and styrene with styrene unit contents of 2.7, 5.7, and 9.5% were synthesized by free radical copolymerization. Poly(ethylenimine)s with benzylated unit contents of 2.4, 6.0, 10.6, and 16.7% were obtained by the reaction of poly(ethylenimine) with benzyl bromide. Polyelect
