The radical induced homo- and copolymerization (with methyl methacrylate) of methyl N-trityl-O-acryloyl-(S)-serine and methyl N-trityl-O-methacryloyl-(S)-serine to give optically active polymers is reported. The resulting polymers are optically active, but show a nonlinear dependence of specific rotation vs. incorporation of chiral monomer.
