Synthesis of optically active polymers by asymmetric catalysts. VIII. Asymmetric polyaddition of dimercaptan to dimethacrylate by optically active amine as catalyst

Optically active polymers could be obtained by the asymmetric polyaddition of tetramethylene dimercaptan to ethylene dimethacrylate using S‐isobutylethylenimine or its polymer as catalyst. Polymer catalysts showed an enhanced activity in the asymmetric polyaddition.
