A process to for polymerizing ethylene in the presence of a metal complex of Structure I, as described herein, which comprises a metal selected from one of Groups 3-6, which is bonded to aryl groups via oxygen and two Z groups. The aryl groups comprise substituents R1a, R1aa, through R15a, R15aa, which are selected from hydrogen, halo, hydrocarbyl, trihydrocarbylsilyl, trihydrocarbylsilylhydrocarbyl, -O(R), -N(R'R"), -S(R"'), or -P(RIVRV); and each R, R', R", R'", RIV and Rv is described herein. Two X groups are also bonded to the metal, and each is halo, hydrocarbyl, or trihydrocarbylsilyl group. Each Z is O, S, N(C1-C40)hydrocarbyl, or P(C1-C40)hydrocarbyl. Groups Y and L form part of a bridge between the Z groups. Y is halo, hydrocarbyl, trihydrocarbylsilyl, trihydrocarbylsilylhydrocarbyl, -O(RVI), -N(RVII RVIII), -S(RIX), or -P(RXRXI); and each RVI, RVII, RVIII, RIX, RXand RXI is described herein. L is (C1-C40)hydrocarbylene or (C1-C40)heterohydrocarbylene. The invention also provides Structure I.
