In at least one embodiment, a catalyst compound is represented by Formula (I): where M is a group 4 metal. Each of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, and R14 is independently hydrogen, or a linear or branched C1-C50 substituted or unsubstituted hydrocarbyl, halocarbyl or silylcarbyl. At least one of R1 and R3 is not hydrogen. Each X is independently a halide or C1-C50 substituted or unsubstituted hydrocarbyl, hydride, amide, alkoxide, sulfide, phosphide, halide, diene, amine, phosphine, ether, or a combination thereof, or two Xs are joined together to form a metallocycle ring, or two Xs are joined to form a chelating ligand, a diene ligand, or an alkylidene.
