Description

Weiche, kältebeständige Massen aus Vinylchloridpolymerisaten Es ist bekannt, daß weichmacherhaltige, weiche Massen aus Vinylchloridpolymerisaten, d. h. aus Polyvinylchlorid oder Mischpolymerisaten aus überwiegenden Mengen Vinylchlorid und anderen, unter den gleichen Bedingungen polymerisierbaren Stoffen, insbesondere Folien oder Überzüge aus diesen Massen, bei gegenseitiger Berührung zum Aneinanderhaften neigen, also eine gewisse Klebwirkung ausüben. Dies ist beispielsweise bekannt bei Regenumhängen aus Weichfolien auf Vinylchloridpolymerisatbasis, wenn man derartige Umhänge zusammenfaltet und längere Zeit bei mäßiger Wärme in diesem Zustand läßt. Die aufeinanderliegenden Teile haften zunächst aneinander, und man kann sie erst unter Anwendung eines gewissen Zuges wieder trennen. Besonders ist dies der Fall, wenn zur Erzielung einer guten Weichheit und besonders einer guten Kältebeständigkeit viel Weichmacher in den Massen enthalten ist oder solche Weichmacher verwendet werden, die, auch schon in geringeren Mengen zugesetzt, sehr weiche und kältebeständige Massen liefern.Soft, cold-resistant compounds made from vinyl chloride polymers It is known that plasticizer-containing, soft compositions of vinyl chloride polymers, d. H. made of polyvinyl chloride or copolymers made from predominant amounts of vinyl chloride and other substances polymerizable under the same conditions, in particular Films or coatings made from these masses, when they come into contact with one another, they stick to one another tend to have a certain adhesive effect. This is known, for example, from Rain capes made of soft films based on vinyl chloride polymer, if you have such Fold cloaks and leave them in this condition for a long time in moderate warmth. The parts lying on top of one another initially adhere to one another, and only then can they be separate again using a certain pull. This is especially the case if to achieve good softness and especially good cold resistance a lot of plasticizer is contained in the masses or such plasticizers are used, which, even when added in small quantities, are very soft and cold-resistant Bulk deliver.

Es wurde nun gefunden, daß weiche, kältebeständige Massen aus Vinylchloridpolymerisaten diese Eigenschaft nicht besitzen und keine Klebneigung haben, wenn sie geringe Mengen, d. h. bis etwa 5 O/o, vorzugsweise zwischen I und 30/0, an Polyäthylen enthalten. Dieser geringe Gehalt an Polyäthylen beeinträchtigt die Homogenität der Massen nicht, was überraschend ist, da Polyäthylen mit Polyvinylchlorid sonst unverträglich ist. Die mechanischen Eigenschaften der Massen sind praktisch die gleichen wie die von entsprechenden Massen ohne einen Gehalt an Polyäthylen. Die Massen gemäß der Erfindung, insbesondere Folien, Überzüge u. dgl., fühlen sich angenehm trocken an und haben keine Neigung, aneinanderzuhaften. It has now been found that soft, cold-resistant compositions made from vinyl chloride polymers do not have this property and have no tendency to stick if they are small amounts, d. H. up to about 5%, preferably between 1 and 30/0, of polyethylene. This low polyethylene content does not affect the homogeneity of the masses, which is surprising, since polyethylene is otherwise incompatible with polyvinyl chloride. The mechanical properties of the masses are practically the same as those of corresponding masses without a content of polyethylene. The masses according to the Invention, in particular foils, coatings and the like, feel pleasantly dry and have no tendency to cling to one another.

Beispiel I 55 Teile Polyvinylchlorid werden mit 45 Teilen Phthalsäuredioctylester versetzt und gegebenenfalls unter Zusatz von Füll- und Farbstoffen auf der heißen Walze geliert. Der Masse werden auf dem Walzwerk 1,50/0 Polyäthylen mit einem mittleren Molekulargewicht von I8000 bis 20000 zugesetzt. Example I 55 parts of polyvinyl chloride are mixed with 45 parts of dioctyl phthalate added and optionally with the addition of fillers and dyes on the hot The roller gelled. The mass will be on the rolling mill 1.50 / 0 polyethylene with a medium Molecular weight from 18,000 to 20,000 added.

Dieses wird ohne weiteres aufgenommen. Man erhält sehr weiche und kältefeste Folien mit trockener Oberfläche. Beim Zusammnfalten haften sie nicht aneinander.This will be added without further ado. You get very soft and Cold-resistant foils with a dry surface. They do not stick when folded to each other.

Beispiel 2 65 Teile eines Mischpolymerisates aus etwa 80 Teilen Vinylchlorid und 20 Teilen eines Acrylsäureesters werden mit 35 Teilen Dibutylphthalat auf einem Mischwalzwerk bei einer Temperatur von etwa I400 verarbeitet. Während der Verarbeitung setzt man 2,50/0 Polyäthylen mit einem mittleren Molekulargewicht von 12000 bis I4000 ZU. Example 2 65 parts of a copolymer composed of about 80 parts of vinyl chloride and 20 parts of an acrylic acid ester are combined with 35 parts of dibutyl phthalate Mixing mill processed at a temperature of about I400. During processing one sets 2.50 / 0 polyethylene with an average molecular weight of 12,000 to I4000 TO.

So hergestellte weiche, sehr gut kältefeste Folien neigen beim Zusammenrollen nicht zum Aufeinanderhaften.Soft, very cold-resistant foils produced in this way tend to roll up not to stick to each other.

Beispiel 3 67 Teile eines Mischpolymerisates aus etwa 85 Teilen Vinylchlorid und I5 Teilen as.Dichloräthylen werden mit 33 Teilen eines Esters aus Triäthylenglykol und Fettsäuren mit einer Kettenlänge von 6 bis 7 Kohlenstoffatomen verarbeitet. Example 3 67 parts of a copolymer composed of about 85 parts of vinyl chloride and 15 parts of as.Dichlorethylene are mixed with 33 parts of an ester of triethylene glycol and processed fatty acids with a chain length of 6 to 7 carbon atoms.

Der Mischung werden etwa 3 0/o Polyäthylen mit einem mittleren Molekulargewicht von etwa 8ooo bis IOOOO zugesetzt. Man erhält Folien mit einer trockenen, nicht zum Aneinanderhaften neigenden Oberfläche.The mixture is about 3 0 / o polyethylene with an average molecular weight added from about 8,000 to 10,000. Films are obtained with a dry, not surface tending to stick together.
