Es ist bekannt, durch Verkleben mehrerer Glasplatten Sicherheitsglas herzustellen. Die dazu verwendeten Klebemittel sollen eine möglichst gute Lichtechtheit aufweisen, transparente Filme bilden, auf Glas haften und bei tropischer Hitze oder winterlicher Kälte weder schmelzen noch undurchsichtig oder brüchig werden. Es sind die verschiedenartigsten Substanzen vorgeschlagen worden, die diese Bedingungen mehr oder weniger gut erfüllen. So wurde in Delmonte »The Technology of Adhesives*, 1947, S. 117, 119 und 125, reines Polyvinylacetat als Klebemittel für die Herstellung von Sicherheitsglas empfohlen. Dieses Polymerisat vermag ebensowenig wie ein in der USA-Patentschrift 2400139 beschriebenes Mischpolymerisat aus Äthylen und Vinylacetat völlig trübungsfreie Klebeschichten zu liefern.It is known to produce safety glass by gluing together several glass plates. The ones used for this Adhesives should have the best possible lightfastness and should form transparent films Glass adhere and neither melt nor opaque or in tropical heat or winter cold become brittle. A wide variety of substances have been proposed to satisfy these conditions meet more or less well. In Delmonte, "The Technology of Adhesives *, 1947, Pp. 117, 119 and 125, pure polyvinyl acetate recommended as an adhesive for the manufacture of safety glass. This polymer is no more capable than one described in US Pat. No. 2,400,139 Copolymer of ethylene and vinyl acetate to deliver completely opaque-free adhesive layers.
Es wurde nun gefunden, daß sich Klebemittel, welche ganz oder teilweise aus Mischpolymerisaten aus 80 bis 20«/« Äthylen und 20 bis 80°/o Vinylester]! bestehen und die unter Anwendung- organischer Lösungsmittel, insbesondere tert-Butanol, hergestellt wurden, zur Herstellung von Sicherheitsglas hervorragend eignen.It has now been found that adhesives which are wholly or partly composed of copolymers from 80 to 20% ethylene and 20 to 80% vinyl ester]! exist and which are made using organic solvents, in particular tert-butanol, are excellent for the production of safety glass suitable.
Die für das erfindungsgemäße Verfahren, anzuwendenden Mischpolymerisate werden- gemäß dem Verfahren der französischen Patentschrift 1 189 387 hergestellt. Als Vinylester werden dabei bevorzugt niedrigmolekulare Ester wie beispielsweise Vinylacetat oder Vinylpropionat verwendet. Wesentlich ist, daß die Polymerisate keine Anteile an Äthylen-Reinpolymerisaten oder Polymerisaten mit sehr niedrigem Vinylestergehalt enthalten, da in einem solchen Falle Filme von verminderter Transparenz und Haftfestigkeit resultieren.The copolymers to be used for the process according to the invention are - according to the process of French patent specification 1,189,387. Low molecular weight vinyl esters are preferred as vinyl esters Esters such as vinyl acetate or vinyl propionate are used. It is essential that the polymers have no proportions of pure ethylene polymers or polymers with a very low level Vinyl ester content, since in such a case films of reduced transparency and adhesive strength result.
Als organische Lösungsmittel können z. B. aliphatische oder aromatische Kohlenwasserstoffe, wie Benzin, Benzol, Toluol, oder Alkohole, wie Methylalkohol, Äthylalkohol, IsopropylalkohoI oder tert-Butylalkohot, verwendet werden1. Eine Anwendung • von Emulgatoren ist hierbei nicht erforderlich und würde mir die Transparenz der Polymerisate herabsetzen. As organic solvents, for. B. aliphatic or aromatic hydrocarbons such as gasoline, benzene, toluene, or alcohols such as methyl alcohol, ethyl alcohol, isopropyl alcohol or tert-butyl alcohol can be used 1 . The use of emulsifiers is not necessary here and would reduce the transparency of the polymers.
Die Herstellung der Mischpolymerisate kann mit Hilfe radikalbildender Substanzen, etwa Peroxyden, z. B. Laurylperoxyd, Diacetylperoxyd, Perkohlensäureester, oder leicht zersetzlicher Stickstoffverbindungen, beispielsweise a,«-Azodiisobuttersäurenitril, erfolgen. Die Polymerisation wird vorteilhaft bei Temperaturen zwischen 30 und ISO0 C unter einem , Äthylendruck von mindestens 10 Atmosphären durch. geführt.The preparation of the copolymers can be carried out with the aid of radical-forming substances, such as peroxides, e.g. B. lauryl peroxide, diacetyl peroxide, percarbonic acid ester, or easily decomposable nitrogen compounds, for example a, «- azodiisobutyronitrile, take place. The polymerization is advantageously carried out at temperatures between 30 and ISO 0 C under an ethylene pressure of at least 10 atmospheres. guided.
Die auf diese Weise hergestellten Produkte lassen sich zur Herstellung völlig ungetrübter Filme mit gutem Haftvermögen verwenden, die eine ausgezeich-Verfahren ziir Herstellung von SicherheitsglasThe products produced in this way can be used to produce completely unclouded films Use good adhesion, which is an excellent process for the manufacture of safety glass

The application of the adhesive to glass can be carried out according to the usual methods, e.g. via solutions or Melting or by laying on in film form. An addition of plasticizers to the polymers is possible, but not required due to the good flexibility and adhesive strength of the products » The glass plates prepared in this way are kept at temperatures of preferably 100 to 140 ° C, expediently at 120 ° C, using a pressure of the order of 2kg / sqcm in the course of Squeezed for 10 to 60 minutes.
