摘要：
A feedstock of one or more C4 to C24 alpha olefins is oligomerized with a metallocene catalyst system to form a polyalphaolefin product mixture. At least a portion of the polyalphaolefin product mixture is then isomerized in the presence of an acid catalyst to form an isomerized polyalphaolefin. The polyalphaolefin may also by hydrogenated, either simultaneously with isomerization or afterwards. The resulting polyalphaolefin has a kinematic viscosity at 100°C of between 1 cSt and 20 cSt and reduced pour point in comparison to the pre-isomerized product.
摘要（中）：
一种或多种C 4至C 24α-烯烃的原料用茂金属催化剂体系低聚以形成聚α-烯烃产物混合物。 然后将至少一部分聚α-烯烃产物混合物在酸催化剂存在下异构化以形成异构化的聚α烯烃。 聚α-烯烃也可以通过氢化，同时异构化或之后。 得到的聚α烯烃在100℃下的运动粘度在1cSt和20cSt之间，与预异构化产物相比具有降低的倾点。
