Mesomorphic glasses below glass

ECTSS-1 and ECTSS-2, they are in the mesomorphous state below the isotropization temperature, Tiso, transiting into mesomorphous glass below glass transition temperature, 7g. 

Isotactic polypropylene crystallizes below 350 K on quick cooling from the melt increasingly as condis glass This conformationally disordered polypropylene had first been described as bdng smectic mesomorphic or paracrystalline ... 

Finally, it is possible that side chains in polymers with very long side chains occur in mesomorphous structures, whereas the main chain is amorphous below the glass transition temperature, and behaves like a normal liquid above it. This type of behavior is observed when the movements of the main and side chains are decoupled by flexible spacer groups joining them together. An example of this is a poly(methacrylate) with the monomeric unit ... 

Isotactic polypropylene is known to crystallize when cooled quickly from the melt into a crystal form which was called a smectic, mesomorphic form. The X-ray diffraction pattern resembled clearly that of a smectic material. Later, this structure was also called para-crystalline to indicate the poor crystalline order. It was found that this structure is metastable below 335 K. At room temperature it has been reported to persist for over 18 months so that it should be called a CD-glass. The proposed transition mechanism to the stable crystal form involves intramolecular helix...
