Living Radical Polymerization 4. Stereospecific Living Radical Polymerization
International Polymer Science and Technology, 2010 Living radical polymerization (LRP) enables the control of molecular weight and molecular weight distribution of polymers synthesized, but it is no effect on stereoregulation (tacticity) of the polymer. With the progress of stereospecific radical polymerizations, several attempts have been made to combine it with LRP to achieve simultaneous control of ...
