Abstract: The invention relates to a process for transitioning from a first continuous polymerization in a gas phase reactor conducted in the presence of a metallocene catalyst to a second polymerization conducted in the presence of a Ziegler-Natta catalyst in the gas phase reactor wherein the metallocene catalyst and the Ziegler-Natta catalysts are incompatible, the process comprising: (a) discontinuing the introduction of the metallocene catalyst into the gas phase reactor; (b) introducing an effective amount of cyclohexylamine into the reactor to at least partially deactivate the metallocene catalyst; (c) introducing an organometallic compound into the reactor and reacting the organometallic compound with cyclohexylamine; (d) degas the gas composition of the reactor and build up a new composition inside the reactor for the second polymerization with the Ziegler-Natta catalyst (e) introducing the Ziegler-Natta catalyst into the reactor.

Abstract: The present invention relates to a polymer composition comprising a linear low-density polyethylene produced in the presence of a single-site catalyst system and 0.01-2.00% by weight of a nucleating agent, the linear low-density polyethylene having a density as determined according to ISO 1183-1 (2012), method A of >900 kg/m3and ≤940 kg/m3, wherein films produced using the polymer composition have a total defected area of ≤50 ppm of surface, the total defected area being the fraction of surface area of the film accounted for by gels having an equivalent diameter of >50 μm. Such polymer compositions are suitable for the production of films having a low oxygen transmission rate and a low water vapour transmission rate.
