Fig. 16-4. Logarithmic plot of loss tangent against frequency reduced to 70 C from data of Fig. 16-3. (Mild. ) Reproduced, by permission, from Polymer Journal.

FIG. 13-4. Loss tangent of sharp poly(vinyl acetate) fractions, plotted logarithmically against frequency reduced to 75 C. Viscosity-average molecular weights from top to bottom, X10" 11.2,26.2, 35.0,78.0. Points with different pip directions refer to different temperatures of measurement. (Oyanagi and Ferry. )...
