摘要：

Local dynamics of cis-1,4-polybutadiene near the glass transition temperature T(g)(=170 K) has been investigated by quasielastic neutron scattering in the energy range of 0.01 meV to 10 meV. It was found that two modes of motions appear near the T(g) in the energy range of ca. 1 meV and 10 approximately 30 mueV. The fast mode arises ca. 50 K below T(g) which corresponds to the so-called Vogel temperature T0. On the other hand, the slow mode appears just above T(g). The natures of the two modes are discussed from viewpoints of glass transition.
