MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202647096657 A) filed by Sabic Global Technologies B. V. on August 10, 2026, for Catalyst System For Multi-Stage Olefin Polymerisation.
Inventors include Li, Lidong; and Al Hubish, Salah.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The invention relates to a catalyst system for polymerisation of olefins, comprising a particulate support material carrying a catalyst compound and a cocatalyst compound, wherein the particulate support material has a particle size D50 of = 20 µm, preferably = 15 µm, more preferably = 5 µm and = 15 µm, and preferably is a silica; wherein the particle size D50 is calculated in accordance with ISO 9276-2 (2014), using particle size measurement as performed in accordance with ISO 13320 (2009), wherein the cocatalyst compound is an organoaluminium compound, and wherein the catalyst system comprises = 20.0 wt% of Al atoms, preferably = 20.0 and = 40.0 wt%, more preferably = 20.0 and = 30.0 wt%, with regard to the total weight of the catalyst system. Such catalyst system combines a small particle size of the catalyst system, which is desirable in for example multi-stage olefin polymerisation processes, with high productivity and production of polymers having appropriately high molecular weight.
