    Abstract: 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 mixture polymer stabilizer mixture, which comprises the polymer stabilizers (i-1) 21 to 29 wt. % of tris(2,4-ditert-butylphenyl) phosphite (CAS-No. 31570-04-4), (i-2) 21 to 29 wt. % of tetrakis-[3-(3,5-ditert-butyl-4-hydroxy-phenyl)-propionyloxymethyl]methane (CAS-No. 6683-19-8), (i-3) 8 to 12 wt. % of a C16-C18 fatty acid calcium salt, (i-4) 36 to 44 wt. % of a calcium oxide, and wt. % of the polymer stabilizers (i-1), (i-2), (i-3) and (i-4) are based on the weight of the polymer stabilizer mixture, 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 mixture at a manufacturing of a 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.
