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, 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.
