关键词:
摘要: Dielectric relaxation measurements have been used to study influences of the molecule topology on secondary process in three phthalate derivatives. The were performed over ten decades frequency and a broad range temperature pressure. isobaric data show thermally activated time all cases, but with different activation energies. isothermal confirm that is insensitive pressure vicinity glass transition temperature. strength, Δɛ decreases lowering below
