Patent number: 11958215Abstract: The invention relates to a method for manufacturing a pellet in a pellet mill, which method comprises the steps of (A) pressing a mixture for compaction by a roller through a nozzle to obtain a strand, and (B) comminuting the strand to obtain the pellet, wherein the mixture for compaction comprises (i) 87 to 97 wt. % of a polymer stabilizer, which is tris(2,4-ditert-butylphenyl) phosphite (CAS-No. 31570-04-4), and (ii) 3 to 13 wt. % of a processing aid, which is a propylene-ethylene copolymer and which possesses a melting enthalpy below 100 J/g at 101.32 kPa. The pellet is useful for a dust-free handling of its polymer stabilizer at a manufacturing of the stabilized polymer. Furthermore, a method for stabilizing a polymer, which is a polyolefin, a polystyrene or a mixture thereof, is disclosed, which comprises the dosing of the pellet to the polymer.Type: GrantFiled: September 7, 2020Date of Patent: April 16, 2024Assignee: BASF SEInventors: Thomas Georg Gfroerer, Shyam Sundar Sathyanarayana, Yean Yik Geoerg, Florian Puch, Jennifer M.

Patent number: 11440231Abstract: The present invention relates to a process for the production of a reinforced polyamide (rP) in an extruder. In this process, a first mixture (M1), a second mixture (M2) and a third mixture (M3) are added into the extruder, and subsequently at least one carbon material is added to obtain a carbon containing polymerizable mixture (cpM) in the extruder. This carbon containing polymerizable mixture (cpM) is polymerized and subsequently devolatilized to obtain the reinforced polyamide (rP). Furthermore, the present invention relates to the reinforced polyamide (rP) obtainable by the inventive process.Type: GrantFiled: August 16, 2017Date of Patent: September 13, 2022Assignee: BASF SEInventors: Florian Puch, Shyam Sundar Sathyanarayana, Yeonsuk Roh, Natalie Beatrice Janine Herle

Publication number: 20220073693Abstract: Foamed pellets contain a block copolymer. The block copolymer is obtained or obtainable by a process involving the reaction of an aromatic polyester (PE-1) with an isocyanate composition (IC), containing at least one diisocyanate, and with a polyol composition (PC). The polyol composition (PC) contains at least one aliphatic polyol (P1) having a number-average molecular weight ?500 g/mol. A process can be used for the production of such foamed pellets. The foamed pellets can be used for the production of a molded body.Type: ApplicationFiled: December 27, 2019Publication date: March 10, 2022Applicant: BASF SEInventors: Frank PRISSOK, Elmar Poeselt, Florian Puch, Dirk Kempfert, Peter Gutmann
