INTERMACROMOLECULAR COMPLEXATION IN SOLUTION AND COMPLEX BLENDS

By progressively increasing the hydrogen bonding interaction, otherwis e immiscible polymer blends composed of modified polystyrene and poly( alkyl methacrylate) can achieve miscibility and complexation successiv ely. The differences in chain arrangement between the slates of mere m iscibility and complex can be detected by a modified NRET fluorescence technique, Immiscibility-miscibility-complexation transitions have be en proved to be of generality for polymer blends with controllable hyd rogen bonding.
