Abstract

Cationic ring-opening polymerization of 3,3-bis(chloromethyl)oxacyclobutane catalyzed by BF₃·OEt₂ was carried out in ionic liquids [bmim]BF₄ and [bmim]PF₆. The influences of BCMO concentration and molar ratio of BCMO/ BF₃·OEt₂ on the molecular weights and yield of PBCMO were investigated. The polymerization in ionic liquids proceed to high conversions, although molecular weights are limited, similar to polymerization in organic solvent such as CH₂Cl₂. Follow a viewpoint of green chemistry, we feel ionic liquid [bmim]BF₄ is superior to [bmim]PF₆. Extracting [bmim]PF₆ from the product using organic solvent as extractant limits its advantage as a green reaction media.
