Asymmetric star polymers: Synthesis and properties

The synthesis and the properties, both in bulk and in solution, of asymmetr ic star polymers are reviewed. Asymmetry is introduced when arms of differe nt molecular weight, chemical nature or topology are incorporated into the same molecule. The phase separation, aggregation phenomena, dilute solution properties etc, are examined from a theoretical and experimental point of view. Recent applications of these materials show their importance in moder n technologies.
