Beschreibung
Zusammenfassung:	Injection molding of thermoplastic polymethylmethacrylate pellets and decorative crosslinked polymethylmethacrylate particles employs an injection nozzle which has a size smaller than at least a portion of the polymethacrylate particles. L'invention porte sur un moulage par injection de pastilles de poly(méthacrylate de méthyle) thermoplastique et de particules décoratives de poly(méthacrylate de méthyle) réticulé. Le moulage emploie une buse d'injection dont la dimension est inférieure à au moins une partie des particules de polyméthacrylate.
