Abstract

έθοδος προς παραγωγή ενός μικροπορώδους πλαστικούμέλους το οποίον περιλαμβάνει :α) τον σχηματισμό μίας συνεκτικής ζύμης δια αναμίξεως μίας θερμοπλαστικής ρητίνης μετά μίας πλαστικοποιητικής ποσότητος ενός πρώτου διαλυτικού και μετά λεπτώς κατανεμημένων τεμαχιδίων ενός πληρωτικού το οποίον περιέχειεν δυνάμενο να καταστεί πτητικό συστατικό εκλυόμενο εκ τούτου δια θερμάνσεως και το οποίο συστέλλεται ουσιωδώς και ανεπιστρεπτί κατά την έκκληση εξ αυτού του ρηθέντος πτητικού συστατικού β)τον σχηματισμό της ρηθείσης ζύμης ήτις περιέχει το διαλυτικόεις ένα διαμορφωμένο μέλος γ) την εξαγωγή του ρηθέντος πρώτου διαλυτικού εκ του ρηθέντος μέλους δι'επαφής αυτού μεθ' ενός δευτέρου διαλυτικού υπό μία θερμοκρασία ουσιωδώς κάτω του σημείου βρασμού οιουδήποτε παρόντος υγρού, του ρηθέντος διαλυτικού όντως ενός το οποίον είναι ικανό να διαλύει του ρηθέν πρώτον διαλυτικό χωρίς να διαλύεται η αναφερθείσα ρητίνη και το αναφερθέν πληρωτικό, οπότε αποπλαστικοποιείται το μέλος τούτο και δ)την ακόλουθο θέρμανση του μέλους τούτου εις μίαν αυξημένη θερμοκρασία αλλά κάτω του σημείου μαλακώσεως της ρητίνηςήτις περιέχεται εκεί μέχρι ότου το ρηθέν πληρωτικό συσταλθεί εντός ς του μέλους δια απελευθερώσεως της περιεκτηκότητος του εις πτητικά.A method for producing a microporous plastic member comprising: a) forming a cohesive dough by mixing a thermoplastic resin with a plasticizer amount of a first solvent and finely divided particles of a filler containing a soluble and soluble solvent which constitutes substantially and irreversibly upon application of said volatile component; (b) the formation of said dough, whether or not it contains a solvate, a shaped member; (c) the extraction of said first solvent from said solvate and a contact solvent thereof. at a temperature substantially below the boiling point of any liquid present, said solvent which is capable of dissolving said first solvent without dissolving said resin and said filler, thereby degreasing said member; of said member at an elevated temperature but below the softening point of the resin is contained therein until said filler is contracted into the member to release its volatile content.
