Description

Lösungs-, Quellungs-, Gelatinierungs- und Weichmachungsmittel Es wurde gefunden, daß freie chlorhaltige aliphatische Karbonsäuren mit wenigstens q. Kohlenstoffatomen sich mit Vorteil als Lösungs-, Quellungs-, Gelatinierungs- und Weichmachungsmittel für die verschiedensten Filmbildner, insbesondere für Vinylpolymerisationsprodukte, wie z. B. Polyvinylchlorid, verwenden lassen. Die chlorhaltigen aliphatischen Karbonsäuren oder auch deren Gemische weisen vor den chlorfreien Verbindungen den Vorteil auf, weit besser mit Filmbildnern verträglich zu sein und aus diesen nicht auszuschwitzen. Sie sind weiterhin weniger flüchtig und -,weniger brennbar. Erhalten werden die Chlorkarbonsäuren in bekannter Weise durch Chlorieren, wobei ein oder mehrere, beispielsweise 3 Atome Chlor in das Molekül der Karbonsäure eintreten können. Geeignete aliphatische Karbonsäuren, die in Form ihrer Chlorderivate als Lösungs-, Quellungs-, Gelatinierungs- und Weichmachungsmittel zur Anwendung kommen können, sind beispielsweise Capronsäure, Caprylsäure, Pelargonsäure, Caprinsäure, Fettsäuregemische mit q. bis 7 bzw. q. bis 9 oder 7 bis 9 Kohlenstoffatomen, Kokosölfettsäuren, Spermölfettsäuren und Alkoxyfettsäuren.Solvents, swelling, gelatinizing and softening agents It was found that free chlorine-containing aliphatic carboxylic acids with at least q. Carbon atoms Advantageously as a solvent, swelling, gelatinizing and softening agent for a wide variety of film formers, especially for vinyl polymerisation products, such as B. polyvinyl chloride, let use. The chlorine-containing aliphatic carboxylic acids or their mixtures have the advantage over the chlorine-free compounds, to be far better compatible with film formers and not to sweat out of them. They are still less volatile and -, less flammable. The Chlorocarboxylic acids in a known manner by chlorination, with one or more, for example 3 atoms of chlorine can enter the molecule of the carboxylic acid. Suitable aliphatic Carboxylic acids, which in the form of their chlorine derivatives as solution, swelling, gelatinizing and plasticizers can be used, are for example caproic acid, Caprylic acid, pelargonic acid, capric acid, fatty acid mixtures with q. to 7 or q. up to 9 or 7 to 9 carbon atoms, coconut oil fatty acids, sperm oil fatty acids and alkoxy fatty acids.

Beispiele i. ioo Gewichtsteile Polyvinylchlorid (nicht nachchloriert) werden mit 3o Gewichtsteilen eines trichlorierten Fettsäuregemisches mit 7 bis 9 Kohlenstoffatomen bei r.to bis 15o ° so lange verknetet, bis eine homogene plastische Masse erhalten worden ist. Diese ergibt nach dem Auswalzen auf Kalanderwalzen Filme, die sich durch gute Elastizität und Kältefestigkeit auszeichnen.Examples i. 100 parts by weight of polyvinyl chloride (not post-chlorinated) are with 3o parts by weight of a trichlorinated fatty acid mixture with 7 to 9 Carbon atoms kneaded at r.to to 15o ° until one homogeneous plastic mass has been obtained. This results after rolling out Calender roll films that are characterized by good elasticity and resistance to cold.

Gleich gutes Gelatiniervermögen zeigt auch die dichlorierte ß-Äthylcapronsäure.The dichlorinated ß-ethylcaproic acid also shows equally good gelatinization properties.

2. 3o Gewichtsteile Chlorkautschuk werden in 3o Gewichtsteilen Tetrahydronaphthalin gelöst und dieser Lösung werden 7 Gewichtsteile eines dichlorierten Fettsäuregemisches mit 6 bis g Kohlenstoffatomen zugesetzt. Es entsteht ein Lack, der nach dem Auftrocknen einen elastischen, schwer brennbaren Film von hoher mechanischer und chemischer Widerstandsfähigkeit hinterläßt.2. 3o parts by weight of chlorinated rubber are added to 3o parts by weight of tetrahydronaphthalene dissolved and this solution is 7 parts by weight of a dichlorinated fatty acid mixture with 6 to g carbon atoms added. The result is a varnish that after drying an elastic, flame-retardant film of high mechanical and chemical properties Leaves resilience.
