- Abstract:
- The synthesis and properties of segmented ABA triblock and (AB), multiblock copolymer
systems with 6,6‘-disubstituted 2,2’-bipyridine (bpy) building blocks B and poly(oxytetramethylene)
soft segments A are described. The access to the disubstituted bipyridines in large scale
quantities was achieved by modification of conventional synthetic routes. In the presence of
copper(1) ions these polymers formed mononuclear [C~(I)(bpy)c~om] plexes in solution through
self-assembly. The complexed copolymers were microphase separated systems in bulk with nano
to mesoscopic superstructures consisting of copper-bpy complex aggregates in a polyether matrix.
The thermal, mechanical and elastomer properties of the block copolymers varied with composition.
