The competing attractive forces between the gel components are responsible for the reentrant transition behavior of hydrophobically modified hydrogels. 

Similarly, Wasserman and coworkers have studied a wide selection of polymeric materials in aqueous solution that are associative of some kind, i.e., that form some sort of self-assembly through non-covalent interactions [96]. Their study mainly deals with hydrogels of hydrophobically modified polymers, aqueous solutions of polymeric micelles created by block copolymers, and hydrogels based on poly (acrylic acid) and macrodiisocyanates. The spin probes of choice were hydrophobic, such as 5- and 16-DSA (see Eig. 2) or even spin labeled polymers. It was, e.g., possible to screen for the effect of chemical stmcture on the gel formation by recording and understanding the local mobility of the hydrophobic, long chain spin probes as a function of temperature.

Typical compressive stress-strain curves of surfactant-containing hydrophobically modified hydrogels are shown in Fig. 15a, where results obtained from 15 separate HM PDMA hydrogel samples at a state of preparation are presented. The... 

In this chapter, recent developments in the design of hydrogels formed via hydro-phobic interactions are reviewed, with a special emphasis on the function of surfactant in their dynamic and mechanical properties. Micellar copolymerization is a simple technique for the synthesis of such hydrogels. A particular advantage of this technique is the blocky structure of the resulting hydrophobically modified polymers, significantly enhancing their associative properties. 

The above p-CD polymer, when mixed with a hydrophobically modified dextran, was also able to form hydrogels, in which photoactive molecules could be entrapped.
