Several kinds of condensation polymerizations which used optically active monomers to synthesize the optically polymers were summarized in this paper.Properties such as thermal stability,solubility and optical activity of the polymers were compared,and its effect mechanisms were discussed.The solubility of the polymers was improved by introducing flexible chain,large side groups,twisted and non-coplanar structures into the backbond.Polymers with flexible chain had lower thermal stability.The structure of the polymers affected its optical activity： large side chain had steric hindrance effect which will stabilize the spiral structure of the polymer.On this basis,the main trends of future development and applications of these kinks of optically active polymers were prospected.
