Producing polyolefin products

A catalyst composition comprising a first catalyst compound and a second catalyst compound that are co-supported forming a commonly supported catalyst system, wherein the first catalyst compound comprises the following formula:

• (C5HaR1 b)(C5HcR2d)HfX2
• wherein each R1 is independently H, a hydrocarbyl group, a substituted hydrocarbyl group, or a heteroatom group;
• each R2 is independently H, a hydrocarbyl group, a substituted hydrocarbyl group, or a heteroatom group;
• a and c are >3;
• a+b =c+d =5;
• at least one R1 and at least one R2 is a hydrocarbyl or substituted hydrocarbyl group;
• adjacent groups R1 and R2 groups are optionally coupled to form a ring;
• and each X is independently a leaving group selected from a labile hydrocarbyl, substituted hydrocarbyl, or heteroatom group, or a divalent radical that links to an R1 or R2 group;
• and the second catalyst compound comprises the following formula:
• wherein each R3 is independently H, a hydrocarbyl group, a substituted hydrocarbyl group, or a heteroatom group;
• R4 is a hydrocarbyl group, a substituted hydrocarbyl group, or a heteoatom group;
• each R5 is independently H, a hydrocarbyl group, a substituted hydrocarbyl group, or a heteroatom group;
• wherein R3, R4, and R5 are the same or different;
• wherein R3, R4, or R5 groups are optionally joined with R3 , R4, or R5 groups on an opposing cyclopentadienyl structure to form one or more bridges if the number of atoms connecting the two cyclopentadienyl rings is >3;
• and each X is independently a leaving group selected from a labile hydrocarbyl, a substituted hydrocarbyl, a heteroatom group, or a divalent radical that links to a R3, R4, or R5 substituent.
