Figure 1
WAXS profiles of it-PB1 crystallized at 313.2, 338.2 and 363.2 K plotted against the modulus of the scattering vector Q. (Q = 4πλ−1sin θ, θ is half the scattering angle, λ is the wavelength used.) The profiles for samples as crystallized and aged are plotted. Peaks shown in the plots of as crystallized samples are indexed with the 200, 220, 213 reflections of the tetragonal form; peaks exhibited in the plots of the aged samples are indexed with the 110, 300, 220 reflections of the trigonal form. |
