 EMI1.1 
 
Es ist bekannt, dass man mit   Weichmachllrgsmittdn plastifizierte Acetylcdlulose sowie casein-   haltige Massen mittels einer dem   Metallspritzg@ssverfahren nach gebildeten Methode durch geeigenete   Spritzvorrichtungen auf geformte Gegenstände verarbeiten kann. 
 EMI1.2 
 in dem sie hergestellt   wurden,   unmittelbar in noch plastischem Zustande in Formen   Mneingespritzt.   So kann man vor der Austrittsstelle der im Patent Nr. 133154 angegebenen Vorrichtung, die zweckmässig als Düse ausgebildet ist, Formen anbringen, in die das noch plastische Polymerisationsprodukt direkt   hineingpspritzt   wird.

   Man kann aber   auch die Poyn@risationsprodukte in zerkleinertem Zustande   in eine Spritzmaschine einführen, dort in plastische Form brirgen und dann in an sich   bekannter   Weise durch Spritzen auf   Forinstiiekg,   weiter verarbeitt n. 



   Nach diesem Verfahren kann man auch Gemische von Polymerisaten sowie Mischpolymerisate von Vinylverbindungen verarbeiten.

 EMI1.1
 
It is known that acetyldululose plasticized with plasticizer and casein-containing masses can be processed by means of a method formed by the metal injection molding process using suitable spraying devices on shaped objects.
 EMI1.2
 in which they were manufactured, directly injected into molds while still plastic. For example, in front of the exit point of the device specified in patent no. 133154, which is expediently designed as a nozzle, molds can be placed into which the polymerisation product, which is still plastic, is injected directly.

   But you can also introduce the polynization products in the comminuted state into a spraying machine, put there in plastic form and then further processed in a manner known per se by spraying on molds.



   This process can also be used to process mixtures of polymers and copolymers of vinyl compounds.

PATENT-ANSPRUCH : Verfahren zur Herst@llung von geformten G genständen durch Verspritzen von plastischen Massen in der dem Metallspritzgussverfahren naelhgebildeten Weise in Formen, dadurch gekennzeichnet, dass man als Spritzgut thermoplastische Polymerisationsprodukte aus Vinylverbindurgen, wie Styrol, Inden, Vinylestern oder Acrylestern verwendet. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the production of shaped objects by spraying plastic masses in molds in the manner similar to the metal injection molding process, characterized in that thermoplastic polymerization products made from vinyl compounds such as styrene, indene, vinyl esters or acrylic esters are used as the spray material. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
