  • Patent number: 9512254
    Abstract: A process for the production of ethylene alpha-olefin copolymers is disclosed. The process may include feeding a catalyst system comprising a supported metallocene, such as a hafnocene, having pores saturated with a selected liquid agent, to a gas phase polymerization reactor. Ethylene and an alpha-olefin may then be contacted with the supported metallocene in the gas phase polymerization reactor to produce an ethylene alpha-olefin copolymer. The copolymer may have a density of less than 0.93 g/cm3, a melt index (I2) of less than 2 dg/min, and a melt flow ratio (I21/I2) of at least 28. To advantageously result in desired effects on catalyst properties and/or polymer properties, the liquid agent may be selected to advantageously manipulate catalyst temperature profiles and/or catalyst-monomer interaction during an initial heating period when the catalyst is first introduced to the reactor.
