Radical polymerization of styrene derivatives bearing N-free amino acid side chains, synergic effect of chirality, and hydrogen bonding for stereoselective polymerization
Radicalpolymerization of styrenederivatives having a series of aminoacid, alanine, glycine, leucine, valine, Boc‐leucine, and Boc‐valine, in the sidechain bound at the C‐terminal was conducted to regulate the stereoinduction system in the propagation step. Isotacticity increased in the polymer main chain, especially in the polymerization of monomers bearing N‐free L‐leucyl and L‐valyl esters in
