Poly (vinyl alcohol) Grafting to Magnetic Poly(urea-formaldehyde) Particles

Magnetic polymer particles, in which polymer matrix is attached to polyvinyl alcohol brushes, was synthesized using grafting from technique. The prepared particles were characterized by different analytical methods such as Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results confirmed that the final particles were successfully synthesized. These particles were employed for absorption and delivery of flutamide as a drug. And using UV-Vis spectrophotometer, influence of different parameters such as pH, time, temperature, and on absorption capacity were examined. The results showed that the maximum drug absorption takes place at pH 6, in the first time interval of 6 min, and is poorly depend to temperature
