Helix-sense-selective radical polymerization of (S)-6-acryloyl-2,2′-bisalkoxy-1,1′-binaphthyl

A series of (S)-6-acryloyl-2,2′-bisalkoxy-1,1′-binaphthyl 1 were radically polymerized to obtain polymers. The optical rotation and the circular dichroism (CD) signal intensity of the radically polymerized poly-1 were close to that of the anionically polymerized poly-1 indicating that the radically polymerized poly-1 should adopt stable preferred-handed helical conformation in solution just as the anionically polymerized poly-1.
