A general rule is that “like dissolves like”, referring to the polarity of the molecules in the solute and solvent. Polarity is the property of a molecule having a more positively charged side and a more negatively charged side. Polar solvents dissolve polar solutes, non-polar solvents dissolve non-polar solutes, generally.

What is water soluble polymer?
Water-soluble polymers are used in combination with other detergent components for optimum cleaning performance and costs. These polymers are designed for use in cleaning applications with high soil loadings, hard water conditions, and moderate temperature.
Why are water soluble polymers used in synthesis?
Water-soluble polymers have been used for the enzymatic synthesis of oligosaccharides because of the high efficiency in the glycosylation reactions, which can be attributed to the polymeric sugar cluster effect326 and the simple purification procedures.327 It has been found that the length of the linker employed to link the acceptor to the polymer has a substantial effect on the glycosylation yield. The linker has to be sufficiently long to avoid any unfavorable steric interactions between the enzyme and the polymer support. The polymer-supported synthesis has been applied toward the synthesis of Le a328 and sLe x. 329 It has also been used in the synthesis of a biomedically important tetrasaccharide 330 whose synthesis mirrors its counterpart in solution phase. Other polymer-supported syntheses of oligosaccharides have also been reported. 99,331–335 Recently, a glycopeptide containing a sialyl Lewis X tetrasaccharide was synthesized using a combination of solid-phase and polymer-supported synthesis.336 Solid-phase synthesis was used to synthesize a peptide containing a Gal residue on Thr. This glycopeptide also contained a bifunctional linker which was used to attach it to a water-soluble polymer, after cleavage from the solid phase. A series of solution-phase enzymatic glycosylations were used to synthesize the sLex glycopeptide. This new strategy takes advantage of both, solid-phase peptide synthesis and solution-phase enzymatic synthesis. Three tandem enzymatic glycosylations were performed on a maleimide-linked GlcNAc residue on thiol-coated glass slides, to synthesize carbohydrate microarray containing sLex. 337 Such a method is very useful for rapidly synthesizing microarrays on glass slides. The solid-phase synthesis of oligosaccharides has also been covered in Chapter 1.09.
How do water soluble polymers interact with water molecules?
Water-soluble polymers may acquire tridimensional structures in an aqueous solution in a reversible way by promoting or increasing physical interactions between polymer chains. While precipitating and collapsing, macromolecules may capture cells and other biomolecules from an aqueous solution together with water molecules, thus creating hydrogel structures that contain active compounds. This feature is especially important for applications in biomedicine. There is an increased interest in this type of physically cross-linked nanostructured hydrogels due to their relative ease of production and the advantage of not having to use cross-linking agents [30]. These agents can affect the integrity of substances to be entrapped (e.g., cell, proteins, etc.) and, consequently, sometimes they need to be removed before application, which is not an easy task.
How are hydrogels formed?
Complex coacervate gels can be formed by mixing a polyanion with a polycation. Finally, ionic polymers can be cross-linked by the addition of a multivalent ion of opposite charges to a polyelectrolyte solution [29]. Vihola et al. [35] synthesized thermally sensitive poly (N-vinylcaprolactam)-based nanostructured hydrogels cross-linked by salicylic acid (SA). The effect of physical cross-linking was studied on the formation and properties of the hydrogels. Different rugs were entrapped into the hydrogels’ structures and the authors observed that they were able to modify the kinetics of drug release, mainly as a function of temperature. It is known that polysaccharides partially modify hydrophobic groups, called hydrophobized polysaccharides, and show unique intermacromolecular self-association in a dilute aqueous solution forming cholesterol-bearing nanostructured hydrogels that are stable, monodisperse, and have a size ranging from 20 to 30 nm [36].
What are the applications of water soluble polymers?
Water soluble polymers have a wide range of industrial applications including food and pharmaceuticals. Polysaccharide and protein based polymers were the two dominant groups among water soluble polymers. Among these polymers, protein based films gained more interest especially in the field of food packaging due to their nutritive values [6]. Gelatin is a polymer that belongs to this category, having better film-forming ability; hence, it is widely studied for its applications in food packaging [7]. Gelatin is obtained from collagen, which exists as a triple helix comprising three discrete and three dimensional α chains interconnected by hydrogen bonds [8]. The collagen which is insoluble in water can be converted into water soluble gelatin by acid or alkali treatments. This process involves the cleavage of large number of covalent cross links. These chemical treatments result in the formation of a three dimensional gel-type network composed of crystallites interlaced with amorphous regions [9]. Gelatin is a transparent and slightly brittle protein, which finds wide applications in the field of foods, drugs, and photographic film applications. It melts when heated and solidifies when cooled again. Together with water, it forms a semi-solid colloid gel. Gelatin forms a solution of high viscosity in water, which sets to a gel on cooling, and its chemical composition is closely similar to that of its parent, collagen. Gelatin is also soluble in most polar solvents. The physical properties of gelatin are given in Table 3.1.
