Molecular Bottlebrushes

Molecular Bottlebrushes

Polymacromonomers consisting of oligostyrene side chains (700 ≤ M n ≤ 5000 g/mol) and of a high molar mass polymethacrylate main chain are shown to exhibit a bottlebrush structure in that the PMA main chain adopts an extremely stiff conformation (i.e., a Kuhn statistical segment length of up to l k...

Zusammenfassung:Polymacromonomers consisting of oligostyrene side chains (700 ≤ M n ≤ 5000 g/mol) and of a high molar mass polymethacrylate main chain are shown to exhibit a bottlebrush structure in that the PMA main chain adopts an extremely stiff conformation (i.e., a Kuhn statistical segment length of up to l k = 2000 Å) which is surrounded by the expanded but still flexible polystyrene side chains.
