Abstract

Thin films of the soluble polydiacetylene derivative P-4-BCMU were prepared from chloroform solution. Duriong the evaporation of the solvent the solution becomes anisotropic before the solid state is reached. The morphology of these films is lamellar, the lamellae being seen edge-on. Lamella thickness is proportional to the chain length of the worm-like polymers. Formation of lamellae is a function of the dwell time of the polymer in the liquid crystalline state. In the early stages lamella thickness is determined by the average number molecular weight. Chain ends are concentrated in disordered interlamellar regions. Approaching equilibrium chain segregation with respect to chain lengths is observed. In addition, the effect of electron irradiation damage in the polymer films is investigated.
