The invention concerns an optically active polymer obtainable by free radical or anionic polymerisation of an optically active ethylene monomer with epoxide function bearing at least a chiral centre with a copolymerisable ethylene monomer. An example of such a polymer is an optically active copolymer consisting of two types of repeat units A and B of formula: (A), (B), wherein R

, B, * and n are such as defined in claim 1. Another example is an optically active monomer consisting of two types of repeat units A and C, A being as defined above and C corresponding to formula (C). Said polymers are useful, optionally after the epoxide functions are opened, for immobilising enzymes, as polymeric matrix for chiral chromatography, as polymeric support for solid phase synthesis, as ligand for preparing transition metal complexes in regioselective catalysis or as chiral inducer in regioselective catalyst.
