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.

Abstract: The present disclosure relates to a method for manufacturing a tablet including (A) filling a starting material, which is in a solid form, in a first open cavity, which is formed by a first punch and a die, to obtain a second open cavity, which is filled at least partly with the starting material, (B) closing the second open cavity by a second punch to obtain a first dosed cavity, (C) compressing the starting material at a compression temperature below 37° C. by moving at least one out of the first punch and the second punch to obtain a second closed cavity, which has a smaller volume than the first closed cavity, which results in formation of a trapped tablet of the starting material in the second closed cavity, (D) removing the trapped tablet to obtain the tablet, which has a tablet temperature below 37° C. directly after removal.

Abstract: The present invention relates to processes for producing microparticles having, in their interior, at least one cavity which is connected via pores to the surface of the microparticles and which have been laden with at least one organic active of low molecular weight. The invention especially relates to a process for loading microparticles with at least one organic active of low molecular weight, wherein the active has been embedded in a matrix and/or the pores of the microparticles have been closed by means of a substance applied to the surface of the microparticles. The invention additionally relates to a process for sealing microparticles laden with at least one organic active of low molecular weight. The invention also relates to compositions of microparticles laden with at least one active of low molecular weight and to the use thereof.
