Gels, amphiphilic

Nagai and colleagues (2006) have also examined the potential of gels formed from the peptide RAD16 to release drugs, and their study examined the diffusion of model compounds through the peptide amphiphile gel.

This review introduces the method of active ester mtheris, and discusses its application to the preparation of a variety erf specialty polymers, including amphiphilic gels, graft copolymers, and side chain reactive and liquid crystalline polymers. The polymerization and copolymerization of activated acrylates by solution and suspension techniques are discussed, and polymer properties such as comonomer distribution, molecular weights, C-NMR spectra and gel morphology are reviewed. Potential applications of these polymers are also highlighted, and the versatility of active ester synthesis as a new dimension of creativity in macromolecular chemistry is emphasized.

Swelling behavior of typical amphiphilic gels obtained by active ester synthesis are compared with those of conventionally available polymers in Table 9. The solvents examined include toluene (TOL), ethyl acetate (EAC), tetrahydrofuran (THF), dichloromethane (DCM), dimethylformamide (DMF), dimethylsulfoxide (DMSO), methanol (MeOH), acetic acid (AcOH) and water. The data in Table 9 clearly demonstrate that amphiphilic copolymer resins obtained by active ester synthesis have general solvent compatibility, ranging fi om toluene and ethyl acetate on the one hand, to acetic acid and water on the other. This swelling behavior compare favorably with those of conventionally available polymers. Styrene based resins are compatible only with the first five solvents listed in Table 9, whereas dimethylacrylamide resins are permeated by the last six solvents.
