Weiterhin betrifft die Erfindung die Verwendung des zweistufigen Emul sionspolymerisats als Verarbeitungshilfsmittel in Polyvinylhalogenid harzmassen.The invention further relates to the use of the two-stage emul sion polymer as processing aid in polyvinyl halide resin masses.
Bei der Verarbeitung von Polyvinylhalogenidharzmassen, insbesondere von Polyvinylchloridharzmassen, zu Formteilen sind kurze Gelier- und Plastifi zierzeiten der Harzmassen besonders wünschenswert, da die Verarbeitungs temperaturen nahe an der Zersetzungstemperatur des Polyvinylhalogenids liegen.When processing polyvinyl halide resin compositions, in particular Polyvinylchloride resin masses to form parts are short gelling and plastifi Decoration times of the resin masses are particularly desirable because of the processing temperatures close to the decomposition temperature of the polyvinyl halide lie.
Um die Gelierungs- und Plastifizierungszeiten von Polyvinylchloridharz massen zu verkürzen, werden den Harzmassen Verarbeitungshilfsmittel zugesetzt, z. B. Copolymere des Methylmethacrylats mit Alkylacrylaten (DE-A-21 26 924 und DE-A-21 01 808) .The gelation and plasticization times of polyvinyl chloride resin Shortening the masses, the resin masses are processing aids added, e.g. B. Copolymers of methyl methacrylate with alkyl acrylates (DE-A-21 26 924 and DE-A-21 01 808).
Aus der DE-A-22 13 214 sind Pfropfpolymerisate aus 50 bis 99 Gew.-% einer Pfropfgrundlage aus überwiegend Methylmethacrylat und 1 bis 50 Gew.-% einer Pfropfhülle aus überwiegend Acrylsäureestern bekannt.From DE-A-22 13 214 graft polymers of 50 to 99% by weight are one Graft base consisting predominantly of methyl methacrylate and 1 to 50% by weight a graft made from predominantly acrylic acid esters.
In der DE-A-23 63 564 sind Pfropfpolymerisate aus 1 bis 49 Gew.-% einer Pfropfgrundlage aus vorwiegend Methylmethacrylat und 51 bis 99 Gew.-% einer Pfropfhülle, welche neben Methylmethacrylat 10 bis 45 Gew.-% eines Acrylsäureesters enthält, beschrieben.In DE-A-23 63 564, graft polymers of 1 to 49% by weight are one Graft base consisting primarily of methyl methacrylate and 51 to 99% by weight a graft which, in addition to methyl methacrylate, contains 10 to 45% by weight of a Contains acrylic acid ester described.
Die bisher bekannten Verarbeitungshilfsmittel vermögen jedoch hinsichtlich der Gelier- und Plastifizierzeiten nicht ganz zu befriedigen.The processing aids known to date, however, are capable of the gelling and plasticizing times are not entirely satisfactory.
Aufgabe der vorliegenden Erfindung war es, diesem Mangel abzuhelfen.The object of the present invention was to remedy this deficiency.
Demgemäß wurden die eingangs definierten Polyvinylhalogenidharzmassen gefunden.Accordingly, the polyvinyl halide resin compositions defined at the outset found.

Suitable reducing agents are, for example, sodium meta bisulfite, sodium hydroxymethanesulfinate and ascorbic acid.
Die Emulsionspolymerisation wird vorzugsweise bei Temperaturen zwischen 30 und 95°C durchgeführt.The emulsion polymerization is preferably carried out at temperatures between 30 and 95 ° C performed.
Durch die Polymerisationstemperatur wird im wesentlichen das Molekular gewicht des gebildeten Polymeren beeinflußt, d. h. je höher die Temperatur, desto niedriger das Molekulargewicht. Die Polymerisationstemperatur kann bei beiden Stufen des Polymerisates gleich oder unterschiedlich sein. Zur Charakterisierung der Molekülgröße dient in der Regel eine Viskositäts messung. Eine gebräuchliche Größe ist der K-Wert nach Fikentscher. In 1%ger Lösung in Tetrahydrofuran kann der K-Wert der beanspruchten Poly merisate zwischen 80 und 150 betragen. Bevorzugt liegt er zwischen 90 und 130, besonders bevorzugt zwischen 100 und 120.The polymerization temperature essentially makes the molecular affects the weight of the polymer formed, d. H. the higher the temperature, the lower the molecular weight. The polymerization temperature can be the same or different in both stages of the polymer. To Characterization of the molecular size usually serves a viscosity Measurement. A common parameter is the Fikentscher K value. In 1% solution in tetrahydrofuran can have the K value of the claimed poly merisates between 80 and 150. It is preferably between 90 and 130, particularly preferably between 100 and 120.
Zunächst werden die Monomeren der 1. Stufe polymerisiert. Die Monomeren der 1. Stufe werden bevorzugt zu mehr als 95 Gew.-% insbesondere zu mehr als 99 Gew.-% auspolymerisiert, bevor mit der Zugabe der Monomeren der 2. Stufe begonnen wird.First, the first stage monomers are polymerized. The monomers the 1st stage is preferably more than 95% by weight, in particular more polymerized as 99 wt .-% before with the addition of the monomers 2nd stage is started.
Die Teilchengröße der Emulsionspolymerisate kann durch die Wahl der Polymerisationsbedingungen eingestellt werden, wie es z. B. in der DE-C 22 30 989 beschrieben ist. Die Teilchengröße hängt z. B. von der Rührergeschwindigkeit ab. Bevorzugt sind mittlere Teilchendurchmesser d50 (Volumenmittel) zwischen ca. 50 und 300 nm.The particle size of the emulsion polymers can be adjusted by the choice of the polymerization conditions, such as. B. is described in DE-C 22 30 989. The particle size depends e.g. B. from the stirrer speed. Average particle diameters d 50 (volume average) between approximately 50 and 300 nm are preferred.
Der Feststoffgehalt der Emulsionen beträgt bevorzugt 30 bis 60 Gew.-%. Das Polymerisat kann aus der Emulsion durch Fällung und anschließende Trock nung oder in einem Verfahrensschritt durch Sprühtrocknung als weitgehend wasserfreies Pulver isoliert werden.The solids content of the emulsions is preferably 30 to 60% by weight. The Polymer can be removed from the emulsion by precipitation and subsequent drying tion or in one process step by spray drying as largely anhydrous powder can be isolated.
Die Sprühtrocknung kann in bekannter Weise durchgeführt werden, wie es z. B. im "Spray drying handbook" (K. Mosters, New York 1985) beschrieben ist. Die Eintrittstemperatur des Trockengases in den Sprühturm liegt zweckmäßigerweise zwischen 100 und 200°C und die Temperatur des getrock neten Pulvers am Ausgang des Sprühturms beträgt bevorzugt 40 bis 100°C.Spray drying can be carried out in a known manner as it is e.g. B. in the "Spray drying handbook" (K. Mosters, New York 1985) is.

Besonders gut verarbeitbare Pulver mit guter Rieselfähigkeit und geringen Verbackungseigenschaften erhält man, wenn die Erweichungstemperatur (Vicat B, bestimmt nach DIN 53 460) oberhalb von 80°C liegt. Zweckmäßiger weise sollte daher der Gesamtgehalt an C1-C18 Alkylacrylat im zweistufigen Emulsionspolymerisat 15 Gew.-% nicht übersteigen. Bei einem höheren Anteil des C1-C18 Alkylacrylats wird die Erweichungstemperatur in unerwünschtem Ausmaß erniedrigt.Powders that are particularly easy to process with good flow properties and low caking properties are obtained if the softening temperature (Vicat B, determined according to DIN 53 460) is above 80 ° C. The total content of C 1 -C 18 alkyl acrylate in the two-stage emulsion polymer should therefore expediently not exceed 15% by weight. With a higher proportion of the C 1 -C 18 alkyl acrylate, the softening temperature is lowered to an undesirable extent.
