Similar structures were also identified in our previous research of PI crystallization, induced by low molecular weight bisimides (BI); it was discovered that upon cooling from their isotropic melts, BI/PI blends underwent a monotropic liquid crystalline transition to form a smectic-like structure (17).

MacKnight and coworkers prepared LCPU using 2,4-toluene diisocyanate (2,4-TDI) [5, 6] or 2,6-toluene diisocyanate (2,6-TDI) [7] with BP-6, and investigated the development of crystallinity and the crystal morphologies of monotropic LCPUs.
Due to the supercooling effect, TPU-6 exhibited monotropic behavior, as observed from the mesophase only on cooling.
If the mesogens exhibit monotropic liquid crystalline behavior, or if the temperature stability range of the mesophase is narrow, the final desired molecular arrangement can be achieved only by modeling the phase transition coupled with the extent of reaction.
Pardey and his co-workers (18-20) synthesized a series of monotropic liquid crystalline poly(ester imide)s from N-(4-(chloroformyl) phenyl)-4-(chloroformyl) phthalimide and different diols with methylene units of 4 to 12 (n) and investigated their ordered structure, phase transition behavior and crystallization behavior.
The morphology of these type II spherulites is very similar to that observed earlier in a monotropic liquid crystalline poly(ester imide) (n = 4) (18).
