Method for preparing polyether based on three-component metal-free catalytic initiation system
The invention discloses a method for preparing polyether based on a three-component metal-free catalytic initiation system. The method comprises the steps of adding an epoxy monomer into a three-component metal-free catalytic initiation system containing hydroxy compounds, organic alkali and boron alkyl to react to obtain the polyether. The method is a currently known ethylene oxide room-temperature open-ring polymerization method with highest catalytic activity since the usage of organic alkali can be reduced to 40ppm and the conversion frequency can be 6000h / l. The polyether has the advantages of no metal residue and no cytotoxicity. The three-component catalytic initiation system adopts ethylene oxide open-ring polymerization, the chain transfer reaction toward the monomer and solvent can be completely avoided while the conversion frequency of 2720h / l can be obtained, and the polyether has the molecular weight of 0.1-400kg / mol, which can be accurately controlled. Furthermore, by utilizing the catalytic initiation system, the (poly) block polyether with controllable molecular weight, block sequence, block proportion and side base combination can be conveniently prepared by continuously adding materials.
