Catalysts that produce polyethylene with broad, bimodal molecular weight distribution

A catalyst compound represented by Formula (I):

• where M is a group 4 metal;
• R3 is a substituted or unsubstituted C4-C40 hydrocarbyl group, wherein the C4-C40 hydrocarbyl group is branched at the β-position;
• R3′ is either:
• (1) methyl, ethyl, or a C3-C40 group having the formula —CH2CH2R where R is an alkyl, aryl, or silyl group, or
• (2) a β-branched alkyl group represented by Formula (II):
• wherein each Ra, Rb, and Rc is, independently, hydrogen, a C1 to C20 alkyl group, or a phenyl group, and each Ra, Rb, and Rc is different from any other Ra, Rb, and Rc such that the catalyst compound has a chiral center on the β-carbon of R3′;
• each of R2, R4, R5, R6, R7, R2′, R4′, R5′, R6′, and R7′ is independently hydrogen, a C1-C40 substituted or unsubstituted hydrocarbyl, halocarbyl, silylcarbyl, alkoxyl, halogen, or siloxyl, or one or more of R4 and R5, R5 and R6, R6 and R7, R4′ and R5′, R5′ and R6′, and R6′ and R7′ are joined to form a completely saturated, partially saturated, or aromatic ring;
• T is a bridging group, and
• each X is independently a halide or C1-C50 substituted or unsubstituted hydrocarbyl, hydride, amide, alkoxide, sulfide, phosphide, halide, or a combination thereof, or two of X are joined together to form a metallocycle ring, or two of X are joined to form a chelating ligand, a diene ligand, or an alkylidene.
