Patent number: 11897169Abstract: 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 ?m and a d90.3 value of more than 20 ?m.Type: GrantFiled: June 18, 2020Date of Patent: February 13, 2024Assignee: BASF SEInventors: Andreas Bauder, Kerstin Muelheims, Michael Freese, Achim Stammer
