Sažetak
A novolac phenol-formaldehyde resin was investigated by thermally
stimulated depolarization current using the integral and
partial measurements in the temperature range from 137 K to
270 K. Two broadened peaks assigned as ~1 and ~2 appeared at
about 160 K and 190 K. The influence of water was investigated.
The analysis of the activation energy, Ea vs. T, and the search for
compensation phenomena were performed. Three different regions
in relaxations were distinguished and the related compensation
temperature s (Te) were determined. Contamination with water increases the polarizability, decreases the structure differences and
relieves the motions in resin. The influence of water was discussed in
the terms of the shifts of Tc's. All the motions were attributed to the
rotation of the phenyl rings with different surrounding structures.
