详细
Relaxation phenomena in polyvinyl alcohol and polyvinyl formal are studied. The internal friction spectra acquired in a free-damped torsional vibrations mode and temperature range from–150 to 120°C of two test samples each contained two distinct loss peaks, designated as α and γ, and weakly expressed β peaks. The acetylation time affects the position of all relaxation loss peaks. The physicochemical characteristics of relaxation processes are calculated. The mechanical relaxation data are confirmed by IR studies.
