The chemorheology of poly (methacrylamide-co-acrylic acid) gel crosslinked by Chromium (III) (Cr ) III ions was investigated using stress-controlled viscometry techniques. This work showed that between various variables, such as polymer and crosslinker concentrations, salinity, pH and temperature, the later parameter had a significant effect on the idle time and processing time as two critical ...

We report on preparation of poly(acrylic acid-co-methyl methacrylate) (PAM) micro- and nanoparticles and, in the subsequent stage, complexation reaction with the active substance - metronidazole (MET). The drug release behavior of MET - loaded PAM micro- and nanoparticles was evaluated in water and phosphate buffered saline (PBS, 0.9% NaCl) at 37ºC. It has been found that introduction of MET in...
