Abstract

έθοδος δια την παρασκευήν λεπτώς διαμερισμένων σωματιδίων πολυμερικής ουσίας περιλαμβάνουσα την ανάμιξιν τουλάχιστον μιας πολυμερικής ουσίας μεθ' ενός διαλυτικού εντός δοχείου την θέρμανσιν του μίγματος υπό πίεσιν εις μίαν θερμοκρασίαν αρκετήν δια την διάλυσιν του πολυμερικού υλικού, την διατήρησινμιας εφαρμοσμένης επί του περιεχομένου του δοχείου πιέσεως καθ' ον χρόνον το περιεχόμενον ψύχεται μέχρι μιας θερμοκρασίας αρκετά χαμηλής ώστε να κατακρημνισθή το πολυμερές από το διαλυτικόν και τον διαχωρισμόν των δια κατακρημνίσεως παραγομένων λεπτώς διαμερισμένων πολυμερικών σωματιδίων από του διαλυτικού υλικού. A process for the preparation of finely divided polymeric particles comprising mixing at least one polymeric substance with a solvent in a vessel, heating the mixture under pressure at a temperature sufficient to dissolve the polymeric material, keeping the content The contents are cooled to a temperature low enough to precipitate the polymer from the solvent and to separate the finely divided polymeric particles produced by the precipitate from the solvent.
