Synthesis of Polypeptide Based Rod-Coil Block Copolymers

 

Controlled radical polymerization
N-Carboxyanhydride (NCA) polymerization for preparation of polypeptides

- Atom Transfer Radical Polymerization
- Reversible Addition/Fragmentation Chain
  Transfer Polymerization
- Nitroxide mediated Polymerization
 
   
- Amin initiated NCA polymerization
- Nickel catalysed NCA polymerization,
   developed by DEMING
 

 
 

Combination of two transition metal catalysed polymerisation to produce well-defined rod coil block copolymers
 
   

 

 

   
Microphase separation due to different domains of the blocks
     Self assembly of block copolymers      into ordered periodic structures

Application: drug carrier

 

Example for self-assembling
