“…Finally, in their theoretical model for polymer complexation, Iliopoulos and coworkers proposed that PEG and PAA complex together along the segments of complementary sequences [27]. They confirmed the consistency of this model with experimental data on polymer blends in solution [27,28]. These results lend support to the concept of strain hardening mediated by hydrogen bond reinforcement of physical entanglements in an IPN.…”

“…This has been recognized from the beginning of PEC formation studies [1][2][3][4][5]132,151,[153][154][155][156]158]. Recently new insights into associative phase separation were reported [254][255][256].…”

“…Although a considerable research efforts have been devoted to investigation of the formation mechanisms and the properties of interpolymer and polyelectrolyte complexes in solutions [1,4,5,132,[154][155][156][157][158], there is a lack of experimental data on the phase behavior of oppositely charged polyelectrolyte blends in a solid state [2,3,159,160].…”

“…These interactions are widely studied because they not only influence the miscibility of various polymeric blends [4,5], but also because the hydrogen-bonded interpolymer complexes (IPC) can be used in drug-delivery systems [6]. The pH, which influences the protonation of the polyacid, is the main factor influencing the hydrogen-bonded interactions in solution.…”

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.
