Disclosed is a method for preparing a high-viscosity polyalphaolefin, chiefly useful as an industrial oil, with high yield under conditions of the room temperature and atmospheric pressure, the method including: prepolymerizing 1-decene or 1-dodecene using a catalyst composed of ethyl aluminum dichloride (EADC) and t-butyl chloride (TBC) to obtain a prepolymer, and bringing 1-octene into contact with the prepolymer used as a catalyst under conditions of the room temperature and atmospheric pressure. Using the method makes it possible to prepare a high-viscosity polyalphaolefin from 1-octene less expensive than 1-decene or 1-dodecene, the polyalphaolefin having a kinetic viscosity of at least 90 cSt at 40 DEG C and a viscosity index of at least 135 to overcome the problem with a low-viscosity polyalphaolefin from 1-decene or 1-dodecene.
