Abstract

The dielectric properties of films obtained through u.v. curing of an acrylated polysiloxane resin were evaluated in the temperature range from −136 to 24‡C. Different relaxation processes (α, Β, γ, δ), characterized by decreasing dielectric relaxation intensities, were evidenced and quantitatively analysed: the α process was attributed to the glass transition process on the basis of the dynamic mechanical spectrum of the film and of its behaviour at different temperatures. The other processes (Β, γ, δ), weaker than the α process, could be attributed to local dipolar motions present, even at low temperatures, in the polymer network.
