Cationic ring-opening polymerization of 3,3-bis (chloromethyl) oxacyclobutane in ionic liquids
摘要:
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.
