✦ Synopsis

Surface tension of the polyacrylamide solution was measured as a function of the polyacrylamide concentration (0 -1000 gm/m 3 ) and temperature (10 -60Β°C). The static contact angles of the polyacrylamide solutions in the range of 0 -1000 gm/m 3 were reported on the polyvinyl chloride and Teflon substrates. Surface tension, static contact angle, and spreading behavior of the polyacrylamide solutions in the presence of different concentrations of NaCl, CaCl 2 , and AlCl 3 are discussed.

A comprehensive study of the rheological properties of aqueous polyacrylamide solutions was carried out. A RheoStress RS100 Haake rheometer was used in the measurements. The concentration of polyacrylamide ranged from 0.25 to 1.0% by weight. This range is sufficiently wide to cover many of the rheol

Rheological properties of aqueous polyacrylamide-sodium chloride solutions are studied using RheoStress RS100. Polyacrylamide concentration was varied from 0.25 to 1.0% by weight, whereas sodium chloride ranged from 0.0 to 10 g L Οͺ1 . This range of concentrations is suitable to study many of the pol

Swelling behavior of polyacrylamide (PAAm) and polyacrylamide-co-polyacrylic acid (PAAm-co-PAAc) gels was investigated in aqueous solutions of monodisperse PAAms with molecular weights ( M V w ) ranging from 1.5 1 10 3 to 5 1 10 6 g/mol. The volume of the gels decreases as the PAAm concentration in
