“…There is a large body of literature on phase diagrams for binary and ternary polymer solutions (Flory 1953;Tompa 1956;Cantow 1967;Utracki 1989) and extensive compilations of data (phase diagrams, cloud points, critical temperatures) for numerous systems (e.g., Wohlfarth 2004Wohlfarth , 2008Koningsveld et al 2001). A few examples of such systems are listed in Table 2.21.…”

“…These include activity of water in the solution and phase separation behavior. The data obtained from these studies are well documented by Wohlfarth [5]. The most widely used methods for activity measurements are vapor pressure osmometry [6], laser-light scattering [7], isopiestic method [7,8], dew point method [9], and sedimentation technique [10].…”

“…In the extremely dilute solution, the second virial coefficient (A 2 ) is a quantitative indicator of the affinity between the polymer and the solvent, i.e., the thermodynamic quality of the solvent for the given polymer Wohlfarth, 2004). The value of A 2 obtained suggests that the 0.1 M sodium nitrite solution containing 0.02% (w/w) sodium azide was a good solvent for galactomannan from C. ferrea seeds.…”

a b s t r a c tThe hydrocolloid extracted from Caesalpinia ferrea var. ferrea seeds purified by membrane filtration was denominated GMPF (14% yield) and contained 75% total carbohydrate and 9% protein, and the mannose to galactose (Man:Gal) ratio was around to 2.1:1.0. The periodate oxidation, methylation and 1D/2D NMR spectra results indicated galactomannan (GM) with a (1 → 4)-linked ␤-d-mannopyranose backbone, partially substituted at O-6 with single-unit ␣-d-galactopyranose side-chains. The splitting of three 13 C signals in the regions of the 4-O-Manp units revealed that the ␣-d-Galp units were irregularly (54%) distributed at the main chain. By rheology, GPC-coupled to multi-detectors, static and dynamic light scattering it was observed that the GM in nitrite solution presented an intrinsic viscosity of 860 mL/g, a polydispersity of 1.55, and a structural parameter (R g /R h ) of 1.77, showing a random coil and flexible conformation, which was confirmed by the Mark-Houwink constant˛(0.63). The results suggest that GMPF can be a new source of GM.
