Method for preparing polybutene by using catalyst containing N-propanol
Disclosed a method for preparing polybutene by using a catalyst including normal propanol, wherein the polybutene has 40 to 70% of vinylidene content and 10% or more of tetra-substituted double bond content by using a complex catalyst including normal propanol as a cocatalyst and a main catalyst such as boron trifluoride. The method comprises: introducing, to a raw reaction material including 10 wt % or more of isobutene, a complex catalyst including normal propanol as a cocatalyst and boron trifluoride as a main catalyst; and polymerizing the raw reaction material at a reaction temperature of −33 to 33° C. under a reaction pressure of 3 to 50 kg/cm2, wherein the vinylidene content is adjusted by adjusting the reaction temperature.
