Controlling the growth of polymer trees: concepts and perspectives for hyperbranched polymers.

This article summarizes basic principles and recent progress in the field of cascade-branched polymers. Methods for the preparation of macromolecules with hyperbranched structures are presented and compared concerning the extent of control over molecular weights and polydispersity. Step-growth and recently developed chain-growth strategies as well as enzyme and transition metal catalyzed polymerizations are discussed with respect to mechanism and future potential.

Molecular Nanocapsules Based on Amphiphilic Hyperbranched Polyglycerols.

Polar dyes can be solubilized in apolar media-molecular nanocapsules with hydrophilic interiors have been prepared (see schematic representation) using polyglycerols with narrow polydispersity and simple esterification with fatty acids. These unimolecular micelles offer attractive potential for a variety of applications ranging from controlled drug release to the design of microreactors and catalysts.

Hyperbranched Polyether Polyols with Liquid Crystalline Properties.

The attachment of mesogens as end groups to hyperbranched polyglycerol (degree of polymerization 22-45; see schematic representation, the rigid mesogens are shown as rods and the flexible alkyl chains as lines) leads to liquid crystalline polymers with narrow polydispersity, whose liquid crystalline behavior is induced by the mesogenic end groups only.
