    摘要: An optically active polymer is obtained by polymerizing a vinyl monomer in the presence of a catalyst which comprises an asymmetric ligand compound of the formula (I) or (II): ##STR1## in which R.sub.1 and R.sub.4 each are ##STR2## R.sub.2, R.sub.3, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 each are an alkyl group having 1 to 10 carbon atoms; X is hydrogen, an alkyl group having 1 to 10 carbon atoms or a halogen; and n is a number of 1 to 4; and an anionic initiator to form a complex with said ligand compound.
