Patent number: 8609807Abstract: The invention relates to a technically advantageous method of producing low-dust granules of polymer additives or polymer additive mixtures. The granule-forming polymer additives are mixed together, the mixture is converted into a workable mass and pressed through an orifice. The pre-shaped strand-like extruded mass is cooled and, while still in a workable state, formed into granules by rolling, impressing, cooling and comminuting.Type: GrantFiled: January 14, 2005Date of Patent: December 17, 2013Assignee: BASF SEInventors: Benjamin Breitenstein, Thomas Georg Gfrörer, Rolf Waldner, Pierre Lutz
