Abstract: Drug releasing process has been studied by small angle laser scattering. The le-vonorgestrel releasing process was followed with ultraviolet spectrometer. The effects of chain motions and the density fluctuations of the polymer on drug releasing process have been discussed.

Key words: poly(methyl-vinylsiloxane), norgestrel, drug release, small angle scattering
