The instant invention provides a method for polymerizing one or more ethylene-based polymers. The method for polymerizing one or more ethylene-based polymers according to the present invention comprises the following steps: (1) selecting ethylene and optionally one or more alpha-olefin comonomers; (2) selecting one or more catalyst systems comprising one or more procatalysts comprising Ti, one or more cocatalysts comprising Al, and one or more self-limiting agents (SLA); wherein the ratio of SLA to Ti is from 5:1 to 40:1 and the ratio of Al to SLA is from 2:1 to 40:1; (3) polymerizing said ethylene and optionally one or more alpha-olefin comonomers in the presence of said one or more catalyst systems via a slurry polymerization process or gas-phase polymerization process in one or more reactors; (4) thereby producing one or more ethylene; wherein said catalyst system has a loss of least 85% of catalyst productivity when the temperature is increased from 85 to 115 C.
