Abstract: | Segregation of eutectic co-units in eutectoid copolymers is behind of forming lamella-shaped extended chain-sequence crystals. These are as cooperative units inhomogeneous microphases (IMP). The mean thickness and the thickness distribution of the IMPs are uniquely related to the lengthdistribution of crystallizable sequences (c-sequences): The primary elements of the colloid structure in eutectoid copolymers are therefore strictly determined by the chain structure. Clusters are formed comprising a finite number of nearly parallel IMPs alternated with amorphous layers. These clusters are the constitutive elements on the secondary level of the colloid-structure. Hosemann's linear paracrystal is used for modelling the cluster structure and for describing X-ray small-angle pattern. |
