“…The phase transition of PVCL is influenced by the presence of ions, surfactants, cosolvents [28,37], but also by other polymers [38,39], especially when they interact through hydrogen bonding [9]. …”

“…They have been shown to interact through hydrogen bonds with proton-acceptor polymers [9][10][11][12][13][14][15][16][17][18]. The increase in the hydrophobicity of the maleic acid comonomer determines the increase of the interpolymer interaction, the addition of hydrophobic forces leading to the precipitation of the hydrogen-bonded complexes and to the increase of the pH at which the complex dissociates [8,17].…”

“…It can also interact through hydrogen bonds with polymers containing carboxylic groups [8,9], being used in the layer by layer deposition for the construction of stimulisensitive thin films [10,11]. It should be mentioned that, from a series of proton-accepting polymers, PVCL is the one that formed the more stable complexes with poly(metacrylic acid) [8,11], the hydrophobic interactions in its case contributing to the strengthening of the complexes [12].…”

The interactions between two synthetic polymers used in biomedical applications, maleic acid-styrene copolymer (MAc-St) and poly(vinylcaprolactam) (PVCL), were investigated in dilute aqueous solution considering the influence of the pH, the added salt and the ratio between the components in the mixture. Hydrogen-bonding interactions between the COOH groups of MAc-St and the C=O groups of PVCL, together with hydrophobic interactions are involved in the formation of the interpolymer complex. The complex is insoluble below pH = 2.85 in aqueous solution, but the addition of NaCl enlarged the pH domain where the precipitation of the complex occurred. When the ratio between the polymers was varied, two maxima of the optical density were obtained: at a 1:1 ratio between the COOH and caprolactam groups, and also at a lower ratio (1:3). Other investigations, like Downloaded by [University of Lethbridge] at 19:13 21 June 20162 the measurements of the turbidity in-situ during mixing, and fluorescence, viscometric and potentiometric measurements were performed in order to understand these interactions. The phase separation of the thermosensitive poly(vinylcaprolactam) in the presence of MAc-St was also studied. The cloud point and the phase transition profile were found to be influenced by the amount of polyacid, as well as by the pH.

Poly(vinylpyrrolidone) (PVP) is one of the most widely used polymers for numerous biomedical, pharmaceutical, personal care, and industrial applications. This chapter begins with an introduction to the solution properties of PVP as manifested in a number of different important parameters to describe the physicochemical properties of the polymer in aqueous solutions. One of the key features of PVP is its good solubility in both water and organic solvents. The complexation of PVP with polyphenols is the basis for a variety of applications. The generation of binding isotherms provides insight into the interactions between polymers and cosolutes. There is an increasing interest in interpolymer complexes or polymer‐polymer complexes formed by mixing two or more interacting polymers in solution, since they are used to generate multilayered soft nanomaterials, such as self‐assembled films or nanoparticles. There has been significant interest in subcritical and supercritical fluid technology as substitutes for organic solvents.
