Description

Verfahren zur Herstellung geformter Gebilde aus Cellulosehydrat Man hat schon thermoplastische Polymerisate mit natürlichen oder künstlichen fadenbildenden Stoffen zu Fäden, Filmen usw. verarbeitet. So hat man z. B. Spinnlösungen aus Viscose Latex oder Lösungen von Polyvinylverbindungen zugesetzt.Process for the manufacture of shaped articles from cellulose hydrate Man already has thermoplastic polymers with natural or artificial thread-forming Fabrics processed into threads, films, etc. So one has z. B. Viscose spinning solutions Latex or solutions of polyvinyl compounds added.

Es wurde nun gefunden, daß man geformte Gebilde, wie Fäden oder Filme, von vorzüglichen Eigenschaften herstellen kann, wenn man zu ihrer Herstellung Mischungen verwendet, die aus Viscose oder Cellulose-Kupferoxyd-Ammoniak hergestellte wäBrige Spinnlösungen und Emulsionen von durch Emglsionspolymerisation hergestellten Polymerisaten enthalten. Als Spinnlösungen kommen in erster Linie Cellulosexanthogenate (Viscose) in Betracht, doch kann man auch Lösungen der Cellulose in Schweitzers Reagens (Kupferseide) verwenden. Als Polymerisate kommen die durch Emulsionspolymerisation erhaltenen Polymerisate organischer und anorganischer Vinylester, Polymerisate von Vinyläthern, Styrol, Acrylsäureestern, Methacrylsäureestern, Acrylnitril, ferner Mischpolymerisate aus Vinylestern oder -äthern, Acrylsäureestern, Styrol und Acrylestern, sowie Butadien und Styrol in Betracht, doch kann man auch andere Mischpolymerisate verwenden.It has now been found that shaped structures, such as threads or films, can produce excellent properties if mixtures are used for their production used, the aqueous produced from viscose or cellulose-copper oxide-ammonia Spinning solutions and emulsions of polymers produced by emulsion polymerization contain. Cellulose xanthogenates (viscose) are primarily used as spinning solutions into consideration, but one can also use solutions of cellulose in Schweitzer's reagent (copper silk) use. The polymers obtained by emulsion polymerization are used Polymers of organic and inorganic vinyl esters, polymers of vinyl ethers, Styrene, acrylic acid esters, methacrylic acid esters, acrylonitrile, and also copolymers from vinyl esters or ethers, acrylic acid esters, styrene and acrylic esters, as well as butadiene and styrene are possible, but other copolymers can also be used.

Beispiel Zu einer spinnreifen Viscoselösung, enthaltend etwa 5,5°/o a-Cellulose und 7°/o Natriumhydroxyd, werden auf je ioo Teile Cellulose 3o Teile einer 3o°/oigen wäßrigen Dispersion des Mischpolymerisates aus 7o Teilen Styrol und 3o Teilen Butadien (berechnet auf festes Mischpolymerisat) zugesetzt. Zur Verbesserung der Verträglichkeit der erhaltenen Mischungen setzt man der Viscoselösung, zweckrhäßig vor dem Eintragen des Mischpolymerisates, eine io°/oige wäßrige Lösung des Einwirkungsproduktes von 2o Mol Äthylenoxyd auf r Mol Oktadecylalkohol zu. Die erforderliche Menge beträgt z bis io°/o.des genannten Einwirkungsproduktes, bezogen auf den Cellulosegehalt der Viscose. Vor dem Verspinnen oder Gießen wird die erhaltene Mischung entlüftet und dann in an sich bekannter Weise verarbeitet. Will man Filme gießen, so empfiehlt sich die Verwendung eines mit Schwefelsäure angesäuerten Ammoniumsulfatbades als Fälschungsmittel. Die erhaltenen geformten Gebilde zeichnen sich durch eine geringe Quellbarkeit aus.Example of a viscose solution ready for spinning, containing about 5.5% α-Cellulose and 7 per cent. sodium hydroxide are converted into 30 parts for every 100 parts of cellulose a 30% aqueous dispersion of the copolymer composed of 70 parts of styrene and 3o parts of butadiene (calculated on the solid copolymer) were added. For improvement the Compatibility of the mixtures obtained is set to the viscose solution, It is advisable to use a 10% aqueous solution before introducing the copolymer of the product of action of 20 moles of ethylene oxide to r moles of octadecyl alcohol. the required amount is z to 10% of the mentioned product of action, based on on the cellulose content of the viscose. Before spinning or casting, the The mixture is vented and then processed in a manner known per se. Do you want films pour, the use of an ammonium sulphate bath acidified with sulfuric acid is recommended as a counterfeit. The molded structures obtained are distinguished by a low swellability.

In analoger Weise werden Lösungen von Cellulose in Schweitzers Reagens verarbeitet.Solutions of cellulose in Schweitzer's reagent are analogous processed.
