説明
<jats:title>Abstract</jats:title><jats:p>Molecular motions in poly(vinylidene fluoride) were studied by the dielectric technique. Three distinct absorption peaks (α<jats:sub>c</jats:sub>, α<jats:sub>a</jats:sub>, and β) were observed in the frequency range from 0.1 cps to 300 kcps and in the temperature range from −66 to 100°C. The molecular mechanisms for these absorptions and their temperature dependence are discussed, and results are compared with x‐ray diffraction and the NMR measurements. It is concluded that the α<jats:sub>c</jats:sub> absorption located at 97°C (1 kcps) is related to molecular motion in the crystalline region. The α<jats:sub>a</jats:sub> absorption located at −27°C (1 kcps) can be interpreted as due to the micro‐Brownian motion of the amorphous main chains. The β absorption located at −47°C (1 kcps) is attributed to local oscillation of the frozen main chains.</jats:p>
