摘　　要：Optically active poly (triphenylmethyl methacrylate) (PTrMA) with a helical conformation of one-handed screw sense could be formed in an anionic asymmetric polymerization in the presence of (-)-sparteine (Sp). Vogt has proved that the absolute configuration of asymmetric centres in the main chain of a right-handed helical PTrMA was all in S configurations according to the polymerization of
