Crystallisation perturbed

The amazingly very low solubility of P-CD in water (about 10 times lower than the solubility of a- and y-CD) is explained by its relatively rigid structure and resulting from this high ability to crystallise [3] or by the xmfavourable 7-fold symmetry of P-CD leading to a perturbation of the water structure [4]. 

In our previous study (17), PE/BMA-salt blends were shown to be conpatible (not in the thermodynamic sense) for a given mixing technique and parameters. It was also pointed out that there is separate crystallisation of PE and EMA-salt in PE/EMA-salt blends, without any perturbation of the crystal structure or degree of crystallinity of the other coiqionent. Since the interactions leading to the compatibilisation of the mechanical properties in PE/EMA-salt blends do not occur in the crystalline phase, they must be present in the amorphous phase.
