Research Abstract

The research purpose is the application of chiral organocatalysts to the precise synthesis of well-defined polymers. The ring-opening of racemic lactide was carried out using (R)-(-)-3,3'-bis(pentafluorophenyl)-1,1'-binaphthyl-2,2'-diyl- phospholic acid as the organocatalyst to produce the high enetioselective living polymerization leading to optically active poly(lactide).
