Abstract

MOP:NERVATION OF ALPHA OLERNS USING METALLOCENE-SSA CATALYST SYSTEMS AND USE OF THE RESULTANT POLYALPHAOLEFINS TO PREPARE LUBRICANT BLENDS This disclosure provides for alpha olefin ollgomers and potyalphaolef Ins (or PAOs) and methods of making the alpha olefin oligomers and PAOs. This disclosure encompasses metaliocene- based alpha olefin oligomerization catalyst systems, including those that Include at least one metallocenci and an acthrator comprising a solid oxide chemically-treated with an electron withdrawing anion. The alpha olefin oligorners and PAOs prepared with these catalyst systems can have a high viscosity Index combined with a low pour point, making them particularly useful in lubricant compositions and as viscosity modifiers.
