Description

Verfahren zur Aktivierung der Mischpolymerisation von ungesättigten Polyesterharzen und Vinylverbindungen Es ist bekannt, daB man die durch Peroxyde anregbare Polymerisation von Vinylverbindungen mit Hilfe von anderen Verbindungen, insbesondere von reduzierenden Verbindungen, aktivieren kann. Diese Verbindungen werden im allgemeinen der zu polymerisierenden Substanz in geringen Mengen zugesetzt. Derartige Polymerisationsaktivatoren sind z. B. Schwermetallsalze, wie Kobaltnaphthenat. Butylsulfit, tertiäre Amine und tertiäre Ph.osphine.Process for activating the interpolymerization of unsaturated Polyester resins and vinyl compounds It is known that peroxides stimulable polymerization of vinyl compounds with the help of other compounds, in particular of reducing compounds. These connections are generally added in small amounts to the substance to be polymerized. Such polymerization activators are, for. B. heavy metal salts such as cobalt naphthenate. Butyl sulfite, tertiary amines and tertiary phosphines.

Auch beider bekannten Mischpolymerisation von Vinylverbindungen mit ungesättigten Polyesterharzen auf Basis von ungesättigten Dicarbonsäuren und Glykolen hat man schon vorgeschlagen, verschiedene Polymerisationsaktivataren zu verwenden. In diesem Falle ist eine starke Aktivierung der Polymerisation besonders wünschenswert, da man solche Mischungen häufig in Formen polymerisiert, wobei es vorteilhaft ist, wenn die Mischpolymerisation innerhalb kurzer Zeit bereits bei Raumtemperatur anspringt.Also in the known copolymerization of vinyl compounds with unsaturated polyester resins based on unsaturated dicarboxylic acids and glycols it has already been proposed to use different polymerization activators. In this case, a strong activation of the polymerization is particularly desirable, since such mixtures are often polymerized in molds, whereby it is advantageous if the copolymerization starts within a short time at room temperature.

Es wurde nun gefunden, daB man die Mischpolymerisation von ungesättigten Polyesterharzen und Vinylverbindungen in technisch einfacher Weise sehr wirkungsvoll aktivieren kann, wenn man den Mischungen aus ungesättigten Polyesterharzen und Vinylverbindungen organische Peroxyde und geringe Mengen von Schwefeldioxyd zusetzt. In der Regel verwendet man o,oo5 bis o,5 %, vorzugsweisse o,oi-.bis -o,2 %, Schwefeldioxyd, bezogen auf das Gesamtgewicht der Mischung.It has now been found that the copolymerization of unsaturated Polyester resins and vinyl compounds are very effective in a technically simple manner can activate if one considers the mixtures of unsaturated polyester resins and vinyl compounds organic peroxides and small amounts of sulfur dioxide added. Usually one uses o, oo5 bis o, 5%, preferably o, oi-.bis -o, 2%, sulfur dioxide, based on the total weight of the mixture.

Die Mischpolymer:isation wird bei diesem Verfahren im allgemeinen innerhalb weniger Minuten angeregt und ist nach Verlauf von einigen Stunden bereits beendet. Die organischen Peroxyde,. :die in Verbindung mit dem Schwefeldioxyd verwendet werden, sollen in der Mischung von ungesättigtem Polyesterharz und Vinylverbindurng löslich sein. Besonders bewährt hat sich als peroxydische Verbindung bei diesem Verfahren Oxy-hydrop.eroxy-- di-cyclohexylperoxyd, das. sich durch Umsetzung von Cyclohexanon und Wasserstoffperoxyd herstellen läßt. Das Schwefeldioxyd kann man der mischpolymeri.sationsfähigen -Mischung oder einer b'zw. beiden Mischungskomponenten zu einem beliebigen Zeitpunkt zusetzen. Gleichzeitig mit dem Schwefeldioxyd kann man auch andere Polymerirationsaktivatoren verwenden.The interpolymer: isation is generally used in this process stimulated within a few minutes and is already after a few hours completed. The organic peroxides. : used in conjunction with sulfur dioxide should be in the mixture of unsaturated polyester resin and vinyl compound be soluble. It has proven to be particularly useful as a peroxidic compound in this case Process Oxy-hydrop.eroxy-- di-cyclohexyl peroxide, which Cyclohexanone and hydrogen peroxide can be produced. The sulfur dioxide can be used the mischpolymeri.sationsbaren -Mixture or a b'zw. both components of the mixture add at any time. Simultaneously with the sulfur dioxide can you can also use other polymerization activators.

Die nach diesem Verfahren zu mischpolymerisierenden ungesättigten Polyesterharze werden vorzugsweise aus ungesättigten Dicarbonsäuren, wie Maleinsäure oder Fumarssäure, und zweiwertigen Alkoholen hergestellt. Als Beispiele für geeignete zweiwertige Alkohole seien Äthylenglykol, Äthylendiglykol, 1,:2- und i, 3-Propandiol, die verschiedenen Butandiole und andere ähnliche Glykole genannt.:Zweckmäß@igisind die ungesättigten Polyesterharze - durch Einbau von gesättigten Dicarbonsäuren, wie Phthalsäure, Bernsteinsäure, Admpinsäure u. dgl., modifiziert. Als Vinylverbindung kommt in erster Linie Styrol in Betracht. Andere geeignete Vinylverbindungen .sind z. B. a-Methylstvrol, Methacryl.säuremethylester und Vinylacetat. Man kann mit den ungesättigten Polyesterharzen gleichzeitig auch mehrere Vinylverbindungen .mischpölymerisieren. Das vorliegende Verfahren ist besonders für die Herstellung von Formkörpern von Interesse. Die Mischpolymerisation wird hierbei in entsprechend ausgebildeten Formen durchgeführt. Die in den nachstehenden Beispielen genannten Teile sind Gewichtsteile.The unsaturated to be copolymerized by this process Polyester resins are preferably made from unsaturated dicarboxylic acids such as maleic acid or fumaric acid, and dihydric alcohols. As examples of suitable Dihydric alcohols are ethylene glycol, ethylene diglycol, 1,: 2- and i, 3-propanediol, the various butanediols and other similar glycols called .:Zweckgenöss@igisind the unsaturated polyester resins - by incorporating saturated dicarboxylic acids, such as phthalic acid, succinic acid, admpic acid and the like. As a vinyl compound styrene comes primarily into consideration. Other suitable vinyl compounds are z. B. a-Methylstvrol, Methacryl.säuremethylester and vinyl acetate. You can with the polymerize several vinyl compounds at the same time with unsaturated polyester resins. The present process is particularly suitable for the production of molded articles from Interest. The interpolymerization is here in appropriately designed forms carried out. The parts mentioned in the examples below are parts by weight.

Beispiel i 65 Teile eines Polyesterharzes von der Säurezahl 40, das auf 2 Mo1 Phthalsäure i Mol Maleinsäure und 3 Mol Propylenglykol enthält, werden in 35 Teilen Styrol gelöst und zur Stabilisierung mit o,oi Teilen Hydrochinon versetzt. Gibt man zu dieser Mischung o,5 Teile Oxy-hydroperoxy-dicyclohexylperoxyd, so setzt bei r8° die Polymerisation nach etwa 2 Tagen ein und ist nach weiteren 5 Tagen so weit fortgeschritten., daß das PolymerisationspTodukt hart erscheint. Wenn man aber in der mischpolymerisationsfähigen Mischung vor Zugabe des Peroxydes o,04 Teile Schwefeldioxyd gelöst hat, beginnt die Polymerisation etwa 15 Minuten nach Zugabe des Peroxydes und ist nach wenigen Stunden beendet.Example i 65 parts of a polyester resin with an acid number of 40 which contains 1 mole of maleic acid and 3 moles of propylene glycol per 2 moles of phthalic acid Dissolved in 35 parts of styrene and treated with o, oi parts of hydroquinone for stabilization. If 0.5 parts of oxy-hydroperoxydicyclohexyl peroxide are added to this mixture, it is set at r8 ° the polymerization starts after about 2 days and is like this after a further 5 days far advanced so that the polymerization product appears hard. But if you do in the copolymerizable mixture before adding the peroxide 0.04 parts When sulfur dioxide has dissolved, the polymerization begins about 15 minutes after the addition of the peroxide and ends after a few hours.

Beisspiel 2 Man löst in der in Beispiel i angegebenen polymerisationsfähigen Mischung o,i Teile Schwefeldioxyd und setzt dann o,5 Teile Oxy-hydroperoxydicyclohexylperoxyd zu. Die Polymerisation springt sofort an und ist nach kurzer Zeit beendet.Example 2 One solves in the polymerizable specified in Example i Mix 0.1 parts of sulfur dioxide and then add 0.5 parts of oxy-hydroperoxydicyclohexyl peroxide to. The polymerization starts immediately and ends after a short time.
