MACROMOLECULES WITH SPECIFIC CONSTITUTION AND SUPRAMOLECULAR STRUCTURES

Segmented triblock and multiblock copolymers consisting of highly flex ible polydisperse segments and molecularly uniform segments of well de fined architecture capable of either the formation df a mesophase, cha infolded crystallites or double-helical metal complexes have been synt hesized; the bulk superstructure as well as the physical and material properties correlated with the primary structure: block copolymers wit h liquid crystalline segments formed microphase separated systems, and the phase behaviour depended on the constitutional composition Multib lock copolymers with symmetrically chainfolded polyurethane hard segme nts and associative groups in the chain fold led to specially shaped l amellar superstructures. Block copolymers with bipyridine containing s egments gave tetracoordinated and double-helical copper(I) complexes w hich segregated resulting in supramolecular polymer systems.
