Abstract: A process for producing particles of a thermoplastic polymer in spherical form involves providing at least one thermoplastic polymer in a molten state and providing an aqueous solution of at least one surface-active substance. The aqueous solution is in a temperature range from 100 to 300° C. The process also involves dispersing the thermoplastic polymer in the aqueous solution to obtain an aqueous solution containing dispersed thermoplastic polymer, which is cooled down to a temperature below the solidification point of the thermoplastic polymer to obtain a suspension containing an aqueous solution and particles of the thermoplastic polymer suspended in a solid state and in spherical form. The particles can be separated from the suspension and, optionally, dried. The particles obtained from the process have a particle size distribution having a d[4,3] value of more than 10 μm and a d90.3 value of more than 20 μm.

Abstract: The invention relates to a process for continuously preparing polyamide oligomers. This comprises continuous conveying of an aqueous solution of polyamide-forming monomers from a reservoir vessel into an oligomerization reactor, heating of the aqueous solution beyond a dissolution or storage temperature, the residence time of the monomer solution in the oligomerization reactor being limited and the pressure or the partial vapor pressure of the water being adjusted such that a conversion of monomers to polyamide oligomers does not exceed a maximum value and/or the polyamide oligomers formed do not phase-separate or spontaneously crystallize in solid form, and continuous discharge of the polyamide oligomers from the oligomerization reactor. A polyamide oligomer preparable by this process can be provided continuously in a mixture with water in a process for preparing a semicrystalline or amorphous, thermoplastically processible polyamide and then postcondensed to give a polyamide. This polyamide can be used for production of moldings by means of injection molding, multicomponent injection molding, injection molding/welding, extrusion, coextrusion, blow molding or thermoforming.
