    • The invention relates to a process for forming a polyalphaolefin, the process comprising the step of polymerizing at least one C8-C12 monomer, preferably a decene such as 1-decene, in the presence of an aluminoxane, an activator and a metallocene to form the polyalphaolefin, wherein the molar ratio of the aluminoxane to the metallocene is less than 250:1. The invention also relates to a process for forming a polyalphaolefin having a desired kinematic viscosity from at least one monomer in the presence of an aluminoxane, an organoboron compound and a metallocene. The process comprises the steps of, inter alia, providing a correlation between (i) the molar ratio of the aluminoxane to at least one of the organoboron compound and the metallocene, and (ii) the kinematic viscosity of the polyalphaolefin to form polyalphaolefins having predictable viscosities.
    • 本发明涉及形成聚α-烯烃的方法,该方法包括在铝氧烷,活化剂和金属茂存在下聚合至少一种C 8 -C 12单体,优选癸烯如1-癸烯的步骤,以形成 聚α-烯烃,其中铝氧烷与茂金属的摩尔比小于250:1。 本发明还涉及在铝氧烷,有机硼化合物和茂金属存在下形成具有来自至少一种单体的所需运动粘度的聚α-烯烃的方法。 该方法特别包括以下步骤:(i)铝氧烷与至少一种有机硼化合物与茂金属的摩尔比之间的相关性,和(ii)聚α-烯烃的运动粘度以形成具有可预测性的聚α-烯烃 粘度。
