The quaternary ammonium salt, 1,1-diallyl-4-formylpiperazinium chloride (3) on cyclopolymerization in water solution in the presence of t-butylhydroperoxide gave water soluble polymer (5). The copolymers of (3) with sulfur dioxide have been prepared in DMSO solvent using ammonium persulfate as the initiator. The composition and phase diagram of the aqueous two-phase systems of the homopolymer (5)...
In the present study, the air-liquid surface and liquid-liquid interfacial activities of hydrophobically modified poly(vinyl alcohol) (PVA) solutions were investigated to determine the effects of NaCl concentration, polymer concentration, time, polymer molecular weight, polymer modification and the average length of the hydrophobic side groups. The hydrophobically modified PVA exhibit high air-liquid...
In this study the rheological behaviour, air-liquid surface and liquid-liquid interfacial activities of solutions of water-soluble associative copolymers of sodium maleate/1-dodecene and sodium maleate/1-hexadecene are investigated with respect to the polymer concentration, temperature, salinity, shear rate and time. The copolymers have been found to exhibit good air-liquid surface and liquid-liquid...
