Description

Verfahren zur Herstellung von leicht löslichen schmelzbaren ' Kunstharzen Es ist bekannt, @daß Methylvinylilcet@oin oidler,desisen Derivate, die in @ i- und@ioider 3-Stelliuug suibsitituiert sind, z.. B,. Methylislop@ropenyllcetio.ni, Benzylisoi- propenyl.lceton, Propylvinylketon;, von der a1il- gemeinen Formel (R und R1 sind Wasserstoff oder Alkyl- oder Aryl- reste) zu Kuinstbiarzen poilymerisiiert werdIen können. Diese Pollymerisatioin wird beispielsweise durch längere Au,flbewahirung, durch Lichit und Wärme oder durch Anwendung von Sanerstoff und sauerstoffabgebenden Mitteln erreicht. Die auf diese Weisse gewonnenen Polymerisate stellen hochschmelzende, schwerlösliche und harte Kuniststofe dair, diie ,aber wegen ihrer geringen Löslichkeit ini:den meisten Lösungsmitteln, zur Her- stellung von Ladken. wenig geeignet sind. Es wurde nun gefunden, d'aß durch Behandlung solcher ungesättigter Ketone von der obengenannten Formel mit Formaldehyd in alkali eher Lösung Kondensaition!sp,radulcto entstehen, dii;e zu Kunst- sitofeni von wesentlnchi "günstigeren Eiigenis@chiaften p,o@lym,erii.siiierb;a@r sind!. Die Kondensation und Poily- meri:sa@tioin dieser Proidiukte erfolgt duechi Anwen- dung, alkal@isic!her Mittel und Wärme. Diurchi Änid!e- rung des, Moilverhältnisses, in dem dhis unigesättigte Keton mit dem Formaldehyd zur Reaktion ge- hraoht wird, kann darüber hinaus! die Lö,siliehkeit der Poilymeri.sate !in versdhiedeneni Lösungsmittelni weitgehend beeinflußt und aibgewandelt werden. Bei einem Malverhältnis i : i ist .diie Löslichkeit in Benzin und Benzol am größte i; bei Überschuiß von Fo,rmald'ehyd bis zum Verhäiltni@s 3.: i erhält man Produkte, die bevorzugt in Alkoholen und Estem löslich sind. Es ist bekannt, Vinylmethyllcetomi mit: Form- aldehyd zu kondensieren. Diese Kondensation er- folgte in schwach saurer oder, neutraler Lösung. Nach der Fällung in schwach saurer oder neutraler Lösung wurde eine Härtung durch !Behandlung mit bas4iisidi!en Stoffen herbeigeführt. In: allen Fällen bil!det siichi aber als Re:aiktions.pmodukt ein. hartes" in! den meinten organischenL,ösungsmitteln: unilösliches und nicht schmelzbares Harz. Demgegenüber wird mit der Erfindung dlie Kon- densation, von Viny.lmetbylkatoni und anderen unr- gies!ätfti:gteni Ketonen,der eingangs erwähniteniFbirmel mit Formaldehyd in afkali-scher Lösung düreh- geführt, und zwar innerhalb- eines, bestimmten Müll- bereiches, wobei ein Kunstharz entsteht, das leicht löslich in den meisten! orgaa-#i-s4chen Lösungsmitteln ist und das sich durch einen genau, bestimmhazen, zwischen ioo bis i5o°- liegenden Erweichungspunkt von den bisher beschriebenen: unsdhmelebaren Harzeni untarscheidet. Es ist ferner bekannt, diie Kondensation vom! bereits polymerisierten( ungesät- tibtern Ketonen mit Farn.alidehyd durchzuführen. Auch im Vergleich zu diesen aus polymeren Vinyl- ketonern mit Formalidehyd gewrmnienieni Kunstharzen ist die Löslichkeit der nach der Erfinidung mit monomeren ungesättigten Ketonen gewonnenen Kun!s,tha,rzie erheblilch größer. Die neuen Podymerieationisp.rodukte unttersidh@ei@den sich hiernach von den bekannten aus Vinylketonen gewonnenen P,olymeri,saten! durch ihre chemische Zusammensetzung, durch ihre bessere Uis@lichkoit in zahlTeichuen! Lösungsmitteln sowie durch ihre physikalischen wie Härte, Er- weidvungspunkt, Lichtbreohungsvermögen, Mhig- keit. Beispi e1 84 Teile Methylisop@ropenylketon werdien: mit ioo Teilen 3o°/o-iger Formaldehydlösung und ioaTeilen zweifach normaler Natronlauge unter Rühren gekocht. Dabei scheidet sich ein. hell ge- färbtes Kondensat bzw. Polymerisat als schweres Öl ,ab.

Dieses Harz isrt iin Benzol leicht löslich. Process for the production of easily soluble, fusible synthetic resins It is known that methyl vinyl acetate oin oidler, desisen Derivatives which suibsitituiert in @ i- and @ ioider 3-Stelliuug are, e.g. Methylislop@ropenyllcetio.ni, Benzylisoi- propenyl acetone, propyl vinyl ketone; from the a1il- common formula (R and R1 are hydrogen or alkyl or aryl residues) can be polymerized to make Kuinstbiarzen can. This Pollymerisatioin is for example by prolonged exposure, by lichite and Heat or by using sanitary cloth and oxygen-releasing agents achieved. The polymers obtained in this way represent high-melting, poorly soluble and hard Plastics dair, diie, but because of their small size Solubility ini: most solvents, to produce position of Ladken. are not very suitable.
