A one-step scalable synthetic procedure results in gels of poly(acrylic acid) (PAA) cross-linked by poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) (Pluronic). The rate of polymerization of acrylic acid in the presence of Pluronic is of 3/2 order in acrylic acid and of 1/2 order in the initiator concentration and is independent of the Pluronic concentration. The formation of cross-linked networks in the synthesis can be: attributed to the hydrogen abstraction by Pluronic radicals from the propagating Pluronic-PAA copolymer. The pluronic-PAA gels exhibit temperature- and pH-dependent swelling in aqueous solutions: Aqueous gel suspensions change the theological behavior in a certain range of temperatures, which depend on the type of Pluronic used. Intraparticle assembly of poly(propylene oxide) segments can be invoked to explain the temperature-dependent;swelling, while interparticle attractive interaction of the dangling chains of Pluronic is responsible for viscosification of the gel suspensions.
