Invariant, small-angle scattering

Fig. 5.6 Small-angle scattering invariant (line), domain spacing (d, open circles) and PE lamellar thickness (/, filled circles) versus time during a series of quenches for a PE-PEE diblock (M = 20kgmol, /pE = 0.55) (Hamley etal. 1997a). The sample was successively quenched from 140°C to 104 C, 100°C, 98°C, 106°C. (Tm (PE) = 108°C for this sample.)...

Fig. 11.11 Small angle scattering invariant of the samples 1PP4 with [rr] = 5.9 mol% (a, a ) and iPP5 with [rr] = 11.0 mol% (b, b ) normalized for the invariant of the unoiiented sample (e = 0) as a function of strain (R, 11.9). Curves a and b are corrected for the decrease in thickness t by assuming that t decreases according to the power law t = to loll)", with to the thickness of the undeformed specimen and i/ = 0.5 as expected for an ideal rubbery material. The correction has been applied for deformations >200%...
