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.

Process for manufacturing granules or powders comprising the steps of (a) providing an aqueous solution or slurry of (A) at least one chelating agent according to general formula (I a) [CH—CH(COO)—N(CH—COO)]MH(I a) wherein M is selected from alkali metal cations and ammonium, same or different, and x is in the range of from 0.01 to 1.0 or (I b) [OOC—CHCH—CH(COO)—N(CH—COO)]MH(I b) wherein M is as defined above, and x in formula (I b) is in the range of from 0.01 to 2.0, and (B) at least one polymer selected from (B1) polyaspartates with an average molecular weight Min the range of from 1,000 to 20,000 g/mole, and (B2) copolymers comprising, in copolymerized form, (α) at least one ester of an ethylenically unsaturated mono- or dicarboxylic acid, and (β) at least one ethylenically unsaturated N-containing monomer, and (b) spray drying or granulating said solution or slurry.

Granules or powders and methods for their manufacture

A computer-implemented method can be used for controlling sorting of plastic compounds. The method involves providing a computer-based database containing entries on a plurality of markers each identifying a specific plastic compound; receiving scan data from a sample of a plastic compound; identifying a marker in the sample of the plastic compound based on the received scan data and the plurality of markers of the database; and sorting of plastic compounds based on the identified marker of the sample of the plastic compound.
