Quenching from the isotropic state

Similar results are observed for polymer P2 (M = 56 500), where T lcn and AHj were additionally followed and found to decrease 

When the polymer is annealed within the biphase, one can observe the simultaneous evolution of three different processes  

homogenization of chain length distribution within their respective 

annihilation of disclination defects within the anisotropic domains. 

Various stages of incomplete demixing are developed when isothermal holding time is insufficient. During homogenization of chain length distribution within the I and N domain boundaries, a gradient of chain

The time-dependent rheological properties of disordered smectics are also peculiar. Figure 10-37 shows apparent G and G" data (labeled MD ) measured for 8CB after a quench from the isotropic state. Quenched samples contain a very high density of smectic defects, which produce elastic-like behavior in G at low frequencies of oscillation. The apparent moduli G and G" in Fig. 10-37 are not true linear viscoelastic moduli, since they were...
