Abstract
Optically active polymethylglycidyl ethers and polymethylglycidyl thioethers were prepared by two ways, viz polymerization of optically active monomers by anionic initiation and stereoelective polymerization of racemic monomers. From chiroptical properties, it was shown that in both case dextrorotatory monomers have R configuration and that the sign of optical activity of polymers is not solvent dependent. Using the same chiral initiator, the stereoelectivity ratio found is higher for the oxirane derivative ( r = 2.0) than for the thiirane ( r = 1.6). For the latter, it was possible to perform an antisteric stereoelective process as in the case of propylene sulphide.
