The main reason that poly(acrylic acid) and poly(methacrylic acid) hydrogels and hydrogel particles have been utilized in oral drug delivery is the fact that they also possess bioadhesive properties (Park and Robinson 1987). Bioadhesive polymers... [Pg.298]

YNTHETIC HYDROGEL POLYMERS, first introduced in the early 1960s, made a major impact, initially in the soft contact lens field, and more recently in other biomedical or specialty applications. The first synthetic poly(2-hy-droxyethyl methacrylate) [poly(HEMA)] hydrogel developed by Wichterle (i) remains very important, as do its copolymers with monomers such as N-vinyl-2-pyrrolidinone, acrylic and methacrylic acids, glycerol methacrylate, various acrylamides, and alkoxyalkyl methacrylates.

Self-oscillations of sweUing and deswelling for the poly(N-isopropylacry-lamide-co-acryhc acid) hydrogels were realized by coupling pH and temperatme in the external solution media. The pH oscillations were also observed for the system consisting of iodate-sulfite-thiosulfate and poly(2-acrylamido-2-methyl-1-propanesulfonic acid) when polymeric acid was substituted for sulfuric acid...
