1. An olefin polymerization process, the process comprising:
contacting a catalyst composition with an olefin monomer and an optional olefin comonomer in a polymerization reactor system under polymerization conditions to produce an olefin polymer; wherein the catalyst composition comprises:
a metallocene compound;
a fluorided solid oxide comprising:
a silica-coated alumina containing from about 10 to about 80 wt. % silica;
from about 0.5 to about 15 wt. % F;
from about 0.5 to about 15 wt. % Zn; and
from about 0.2 to about 1.2 wt. % B; and
optionally, a co-catalyst.
