Description

Beschleunigen der Kristallstrukturumlagerung von Polybuten-(1) Die Erfindung betrifft die Verwendung von 0,1 bis 20 Gewichtsprozent an höheren aliphatischen Carbonsäuren zum Beschleunigen der Kristallstrukturumlagerung von Polybuten-(1).Accelerating the crystal structure rearrangement of polybutene- (1) Die The invention relates to the use of 0.1 to 20 percent by weight of higher aliphatic Carboxylic acids to accelerate the crystal structure rearrangement of polybutene- (1).

Polybuten-(1) bildet zwei Modifikationen, eine instabile Modifikation II und eine stabile Modifikation I. Aus der Schmelze, d. h. nach dem Granulieren und insbesondere nach der thermoplastischen Verarbeitung, bildet sich die Modifikation II, welche sich normalerweise bei Raumtemperatur und ohne Druckbeanspruchung erst innerhalb von etwa 6 bis 7 Tagen in die stabile Modifikation umlagert. In der Modifikation II ist das Polybuten-(1) mechanisch kaum beanspruchbar, da es zu weich ist und zu geringe Festigkeit besitzt; die Fließfestigkeit beträgt nur 80 bis 100 kg/cm2 bei Modifikation I. Polybutene- (1) forms two modifications, one unstable modification II and a stable modification I. From the melt, i.e. H. after granulating and especially after thermoplastic processing, the modification forms II, which is normally only at room temperature and without compressive stress rearranged into the stable modification within about 6 to 7 days. In the modification II, the polybutene (1) can hardly be stressed mechanically because it is too soft and too has poor strength; the flow strength is only 80 to 100 kg / cm2 Modification I.

Es ist aus den ausgelegten Unterlagen des belgischen Patentes 612 416 bekannt, daß man Niederdruckpolyolefine durch Zusatz von 0,01 bis 1 Gewichtsprozent eines Natrium- oder Kaliumsalzes organischer Säuren mit einer Kettenlänge von 8 bis 30 Kohlenstoffatomen im Korrosionsverhalten, das aus den Katalysatorresten herrührt, verbessern kann. Gleichzeitig wird die Gleitfähigkeit verbessert. Dieses Verfahren ist nur an Niederdruckpolyäthylen erläutert. It is from the laid out documents of Belgian patent 612 416 known that low-pressure polyolefins by adding 0.01 to 1 percent by weight of a sodium or potassium salt of organic acids with a chain length of 8 up to 30 carbon atoms in the corrosion behavior resulting from the catalyst residues, can improve. At the same time, the lubricity is improved. This method is only explained for low-pressure polyethylene.

In Fällen, in denen man keine verbesserte Gleitwirkung benötigt und auch eine Korrosionsverhinderung nicht erforderlich ist, besteht also keine Veranlassung zum Zusatz der Kalium- und Natriumsalze. In cases where there is no need for improved lubricity and corrosion prevention is not necessary either, so there is no need for the addition of the potassium and sodium salts.

Da Polyolefine, wenn sie, was häufig der Fall ist, mit phenolischen Verbindungen stabilisiert sind, in Gegenwart basischer Stoffe, wie der genannten Alkalisalze, zu unerwünschten Verfärbungen neigen, boten sich diese Salze dem Fachmann nicht an, um ein ganz andersartiges Problem beim Polybuten-(1) zu lösen.As polyolefins if they, which is often the case, with phenolic Compounds are stabilized in the presence of basic substances, such as those mentioned Alkali salts, which tend to discolour, these salts presented themselves to the person skilled in the art not to solve a very different problem with polybutene- (1).

Der Erfindung liegt die Aufgabe zugrunde, die Modifikationsumwandlung des Polybutens-(1) zu beschleunigen. The invention is based on the object of the modification conversion of polybutene- (1) to accelerate.

Diese Aufgabe wird erfindungsgemäß wie oben beschrieben gelöst. This object is achieved according to the invention as described above.

Zu den höheren aliphatischen Carbonsäuren zählen insbesondere z. B. Stearinsäure und Palmitinsäure. The higher aliphatic carboxylic acids include in particular z. B. stearic acid and palmitic acid.

Die Zusätze werden dem Niederdruckpolybuten-(1) zweckmäßig vor der Granulierung beigemischt. The additives are the low pressure polybutene (1) appropriate before Granulation added.

Beispiel 1 90 Gewichtsteile Niederdruckpolybuten-(1) mit einem I5-Wert von 0,6 (bei 1900C gemessen) werden mit 10 Gewichtsteilen Stearinsäure gemischt. Die aus der Mischung hergestellte Preßplatte (bei 180"C ge- preßt) hat folgende Eigenschaften (nach 24 Stunden Lagerung): Fließfestigkeit Shore-Härte D Kugeldruckhärte kglcm2 | Shore Härte 10 Sekunden 202 | 62 | 364 kg Preßplatten aus dem gleichen Polybuten ohne den erfindungsgemäßen Zusatz haben nach 24 Stunden Lagerung folgende Eigenschaften: Fließfestigkeit 128 kg/cm2, Shore-Härte D 50; die Kugeldruckhärte ist nicht meßbar, die Platte ist zu weich.Example 1 90 parts by weight of low-pressure polybutene- (1) with an I5 value of 0.6 (measured at 1900 ° C.) are mixed with 10 parts by weight of stearic acid. The press plate produced from the mixture (pressed at 180 "C) has the following properties (after 24 hours of storage): Flow strength Shore hardness D Ball indentation hardness kglcm2 | Shore hardness 10 seconds 202 | 62 | 364 kg Press plates made from the same polybutene without the additive according to the invention have the following properties after storage for 24 hours: flow strength 128 kg / cm2, Shore hardness D 50; the indentation hardness cannot be measured, the plate is too soft.

Beispiel 2 Aus Niederdruckpolybuten-(1) und Palmitinsäure wird die in der Tabelle angegebene Mischung hergestellt. Aus der Mischung werden bei 180"C Preßplatten hergestellt. Die hergestellten Preßplatten haben folgende Eigenschaften nach einer Lagerung von 48 Stunden: Zusatz | Shore-Härte D Kugeldruckhärte 10 Sekunden Ohne Zusatz 51 nicht meßbar, zu weich 10 °/0 Palmitinsäure 64 340 Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Zusätze neben einer Beschleunigung der Kristallisation eine Beschleunigung der Kristallstrukturumlagerung von der instabilen Modifikation II zur stabilen Modifikation I bewirken.Example 2 The mixture given in the table is prepared from low-pressure polybutene (1) and palmitic acid. Press plates are produced from the mixture at 180 "C. The press plates produced have the following properties after storage for 48 hours: Addition | Shore hardness D ball indentation hardness 10 seconds Cannot be measured without addition 51, too soft 10 ° / 0 palmitic acid 64 340 The advantages achieved with the invention are in particular that the additives accelerate the crystal structure rearrangement from the unstable modification II to the stable modification I in addition to accelerating the crystallization.

Während die Umlagerung des reinen Polybutens-(1) bei Raumtemperatur und Atmosphärendruck ohne Einwirkung weiterer äußerer Druck- oder Zugspannungen von Modifikation II nach I etwa 6 Tage dauert, ist sie bei den Polybuten-1-Mischungen schon nach 1 bis 2 Tagen beendet. Dadurch läßt sich das mit den Zusätzen gemischte Polybuten-(1) in äußerst vorteilhafter Weise für die Extrusion von Profilen wie Rohren einsetzen, welche alsbald ihre maximale Festigkeit erreichen, und zwar bereits nach 1 bis 2 Tagen, also innerhalb der mindestens üblichen Verlade-, Versand- und Ingebrauchnahmezeit. Der Vorteil, den die neue Mischung, beispielsweise in Form von Rohren auf dem Bausektor, bietet, liegt auf der Hand.During the rearrangement of the pure polybutene- (1) at room temperature and atmospheric pressure without the influence of further external compressive or tensile stresses from Modification II to I lasts about 6 days, it is the case with the polybutene-1 mixtures finished after 1 to 2 days. This allows the mixed with the additives Polybutene- (1) in an extremely advantageous manner for the extrusion of profiles such as Use pipes that will soon reach their maximum strength, and that already after 1 to 2 days, i.e. within the at least usual loading, shipping and Time to use. The advantage of the new mix, for example in terms of shape of pipes in the construction sector, offers, is obvious.

Durch die kristallisationsbeschleunigende Wirkung der Zusätze wird auch die Oberflächenhärte schon nach kurzer Zeit erreicht, während sie beim reinen Polybuten-(1) erst nach 6 bis 7 Tagen erreicht ist. Diese Beschleunigung der Kristallisation bewirkt ferner den wesentlichen technischen Fortschritt, daß eine Versprödung des Polymerisates durch Bildung uner- wünschter Kristallisationsformen hintangehalten wird. The additives accelerate crystallization even the surface hardness is reached after a short time, while it is pure Polybutene- (1) is only reached after 6 to 7 days. This acceleration of crystallization also causes the essential technical progress that an embrittlement of the Polymer by forming un- desired forms of crystallization will.

Vor allem aber kann man nunmehr Formkörper erzeugen, die schon kurz nach ihrer Herstellung vollkommen formbeständig sind.Above all, however, you can now produce moldings that have already been short are completely dimensionally stable after their manufacture.
