Abstract
In the present paper the dielectric properties of solid solutions of 4 -nitroaniline in a poly(methyl methacrylate) matrix have been measured in the frequency range 20-10(6) Hz and the obtained data have been co mpared with those for pure poly(methyl methacrylate). It is shown that the presence of the solute has a strong influence on the relaxation p rocess of the polymer and this is ascribed to the formation of hydroge n bonds between the amino group of the solute and acetate side groups of the polymer.
