Description

Verfahren zur Herstellung von harzartigen Kondensationsprodukten Es wurde gefunden, daß wertvolle elastische Kondensationsprodukte erhalten werden, wenn Verbindungen, die eine oder mehrere Äthylenoxyd-oder Propylenoxydgruppen im Molekül enrthalten, mit Ketodilaktonen umgesetzt werden.Process for the preparation of resinous condensation products Es it was found that valuable elastic condensation products are obtained, if compounds which have one or more ethylene oxide or propylene oxide groups in the Molecule contained, to be reacted with ketodilactones.

Als alkylenoxydgrugpenhaltige Verbindungen seien beispielsweise genannt: Äthylenoxyd, Phenoxypropenoxyd,Toluolsulfosäure-2, 3-epoxy-propylmethyl-amid, Verbindungen, die aus Polyphenolen, beispielsweise Biphenol, Resorcin, lDiphenolaceton mit Epichlorhydrin oder Dichlorhydrin in Gegenwart von Alkalien erhältlich sind.Examples of compounds containing alkylene oxide gravel are: Ethylene oxide, phenoxypropene oxide, toluenesulfonic acid-2, 3-epoxy-propylmethyl-amide, compounds, those made from polyphenols, for example biphenol, resorcinol, diphenol acetone with epichlorohydrin or dichlorohydrin are available in the presence of alkalis.

Als Ketodilaktane seien beispielsweise genannt: Ketopimel-insäuredilakton, Benzoylglutarsäuredilakton.Examples of ketodilactans that may be mentioned are: Ketopimel-insäuredilakton, Benzoylglutaric acid dilactone.

Die Mischungen aus den Epoxydveribin@dungen und den Ketodilaktonen sind bei Raumtemperatur lange haltbar. Bei erhöhterTernperatur, inbesondere i5o bis 25o°, liefern sie auf Glas oder Metall sehr fest haftende, elastische Schichten. Sie sind deshalb besonders geeignet für Lacke, sonstige Überzüge und Verklebungen, wobei Scherfestigkeiten von 25obis 3oo kg/cm2 erreicht werden. Die Umsetzung kann beliebig unterbrochen und später weitergeführt werden. Füllstoffe und Weichmacher können den Misch engen zugesetzt werden.The mixtures of the Epoxydveribin @ dungen and the Ketodilaktonen can be kept for a long time at room temperature. At higher temperatures, especially i5o up to 25o °, they provide very firmly adhering, elastic layers on glass or metal. They are therefore particularly suitable for paints, other coatings and bonds, whereby shear strengths of 25 to 300 kg / cm2 can be achieved. The implementation can interrupted at will and continued later. Fillers and plasticizers can be added to the mix.

Beispiel ioo g eines Epoxydproduktes, hergestellt aus Diphenolaceton und Glycerindichlorhydrin in Gegenwart von Natronlauge, werden mit 35 g Ketopi,meli.nsäuredilakton bei 70° gemischt. Die Mischung wird in eine Tube aus dünner AI-Folie gegossen und bei i8o° 3 Stunden gehärtet. Nach dem Erkalmen wird die dünne Folie abgezogen. Es ist ein zähes, hartes, unlösliches Produkt entstanden (Kunststoftl, welches sich sägen und bohren läßt.Example 100 g of an epoxy product made from diphenol acetone and glycerol dichlorohydrin in the presence of sodium hydroxide solution are mixed with 35 g of Ketopi, meli.nsäuredilakton mixed at 70 °. The mixture is poured into a tube made of thin Al foil and Hardened at 180 ° for 3 hours. After the calving, the thin film is peeled off. It is a tough, hard, insoluble product was created (plastic, which saw itself and let them drill.
