| abstract |
The present disclosure provides alpha olefin oligomers and polyalphaolefins (or PAOs), and methods of making the alpha olefin oligomers and PAOs. The present disclosure includes metallocene-based alpha olefin oligomerization catalyst systems, including those systems comprising at least one metallocene and an activator comprising a solid oxide chemically treated with an electron-withdrawing anion. Alpha olefin oligomers and PAOs produced with these catalyst systems can have high viscosity indices combined with low pour points, making them particularly useful in lubricant compositions and as viscosity modifiers. |
