Description

Polymerisation von Vinylverbindungen mit aktivierten Doppelbindungen in Emulsion Es wurde gefunden, daB man eine starke Beschleunigung bei der Polymerisation von Vinylverbindungen mit aktivierten DoppcIbindungen in Emulsion erzielen kann. wenn man die Polymerisation in Gegenwart von wasserlöslichen Acetylenalkoholen, beispielsweise Propargylalkohol, i # q.-Butindiol oder Methylbutinol, ausführt. Als Vinylverbindungen, deren Polymerisation durch die genannten Acetylenalkohole besonders beschleunigt oder bei wesentlich niedrigeren Temperaturen als sonst üblich ausgeführt werden kann, seien beispielsweise Vinylester organischer Säuren, Vinylchlorid, Styrol, Butadien, seine Homologen und Chlorsubstitutionsprodukte, Vinylketone, Vinylcarbazol, asymmetrisches Dichloräthylen, * Divinylbenzol sowie Mischpolymerisate dieser Verbindungen entweder untereinander oder mit weiteren unter den gleichen Bedingungen polymerisierbaren ungesättigten organischen Verbindungen genannt.Polymerization of vinyl compounds with activated double bonds in emulsion It has been found that there is a strong acceleration in the polymerization of vinyl compounds with activated double bonds in emulsion. if the polymerization is carried out in the presence of water-soluble acetylene alcohols, for example propargyl alcohol, i # q.-butynediol or methylbutynol. As vinyl compounds, their polymerization by the acetylene alcohols mentioned particularly accelerated or at significantly lower temperatures than usual can be performed, for example vinyl esters of organic acids, vinyl chloride, Styrene, butadiene, its homologues and chlorine substitution products, vinyl ketones, vinyl carbazole, asymmetric dichloroethylene, * divinylbenzene and copolymers of these compounds polymerizable either with one another or with others under the same conditions called unsaturated organic compounds.

Die Polymerisation wird in der für Emulsionspolymerisationen üblichen Weise, vorteilhaft in Gegenwart von sauerstoffabgeben den Stoffen, insbesondere organischen ode anorganischen Peroxyden, Persulfaten ode Persäuren, ausgeführt. Als Emulgiermitte eignen sich solche auf Basis höherer Fett Säuren, beispielsweise Alkalisalze oder aucl Tauride höhermolekularer Fettsäuren, ferne auch SchwefeIsäureester höhermolekulare Fettalkohole, sulfonierte Fettsäureamide, An Lagerungsverbindungen von mehreren Mole külen Äthylenoxyd an hydroxyl- oder amino gruppenhaltige, langkettige organische. Ver Bindungen, alkylierte Naphthalinsulfonsurei sowie Umsetzungsprodukte von i ode mehreren Molen langkettiger aliphatische Amine mit ß # ß'-Dichlordiäthyläther.The polymerization is carried out in that customary for emulsion polymerization Way, advantageously in the presence of oxygen-releasing substances, in particular organic or inorganic peroxides, persulfates or peracids. Suitable emulsifying agents are those based on higher fatty acids, for example Alkali salts or also taurides of higher molecular weight fatty acids, and also sulfuric acid esters higher molecular weight fatty alcohols, sulfonated fatty acid amides, storage compounds from several moles of ethylene oxide to hydroxyl or amino group-containing, long-chain organic. Ver bonds, alkylated Naphthalenesulfonsurei and reaction products of i or several moles of long-chain aliphatic amines with ß # ß'-dichlorodiethyl ether.

Beispiel In einer Lösung von 40 Gewichtsteilen eine Umsetzungsproduktes aus i Mol ß # ß'-Dichlor diäthyläther mit a Mol eines höhermoleku Laren Amins, das aus Paraffinoxydationspro dukten über die Fettsäuren, Fettsäurenitrill und Reduktion dieser gewonnen wurde, in iooo Gewichtsteilen Wasser werden 675 Gewichtsteile Fumarsli.urediäthylester und 265 Gewichtsteile Butadien emulgiert. Die Emulsion wird mit o,5 Gewichtsteilen Kaliumpersulfat, 4 Gewichtsteilen 3o(i;oigem Wasserstoffperoxyd und 5o Gewichtsteilen i # 4-Butindiol versetzt und unter kräftigem Rühren auf 40° gehalten. Es tritt dabei Polymerisation ein, die nach 4 Stunden bereits beendet ist, während ohne den Zusatz des Butindiols nach etwa 15 Stunden nur 6o bis 65% polymerisiert sind. Bei Anwendung geringerer Mengen i # 4-Butindiol erhöht sich die Polymerisationszeit; so benötigt man zur vollkommenen Polymerisation des Gemisches bei einem Zusatz von 2,5#'o i # 4-Butindiol 5i/2 bis 6 Stunden, bei Zusatz von i % 8 Stunden, während ohne Zusatz 24 bis 3o Stunden erforderlich sind.Example In a solution of 40 parts by weight of a reaction product of 1 mole of ß # ß'-dichloro diethyl ether with a mole of a higher molecular amine, which was obtained from Paraffinoxydationspro products via the fatty acids, fatty acid nitrile and reduction of these, in 100 parts by weight of water, 675 parts by weight of Fumarsli .ured diethyl ester and 265 parts by weight of butadiene emulsified. The emulsion is mixed with 0.5 parts by weight of potassium persulfate, 4 parts by weight of 30% hydrogen peroxide and 50 parts by weight of i # 4-butynediol and kept at 40 ° with vigorous stirring. Polymerization occurs, which is already over after 4 hours. while without the addition of the butynediol, only 60 to 65% polymerized after about 15 hours. If smaller amounts of i # 4-butynediol are used, the polymerization time is increased; # 4-butynediol 5½ to 6 hours, with the addition of i% 8 hours, while without addition 24 to 30 hours are required.
