Abstract:
1. A polyalphaolefin comprising 75 wt % to 99 wt % 1-decene monomers and 1 wt % to 25 wt % propene monomers said polyalphaolefin having a branch level greater than 20%, a kinematic viscosity of between 20 and 1000 cSt at 100° C. and a pour point that is less than −15° C., wherein said polyalphaolefin is formed by polymerizing a mixture of decene and propene monomers in the presence of a catalyst system comprising a metallocene catalyst and an aluminoxane co-catalyst, said metallocene catalyst having the formula wherein M is zirconium, q is 2, X is halogen, (Cp (Cp R wherein R 4 and R 5 are selected from cycloalkyl, aryl or alkaryl.
