Description

Verfahren zur Herstellung linoxynartiger Massen Bei der Polykondensation von Pentaerythrit mit Dicarbonsäuren erhält man keine verwalzbaren Felle, auch nicht, wenn weichmachende Komponenten, wie G1vkole, einkondensiert werden.Process for the production of linoxyn-like masses During polycondensation pentaerythritol with dicarboxylic acids does not produce any millable skins, not even when plasticizing components such as glycols are condensed in.

Es wurde nun gefunden, daß man aus Pentaerythrit, 2- oder 3wertigen Alkoholen und Dicarbonsäuren linoxynartige Massen erhält, wenn man die Kondensation dieser Stoffe in Gegenwart von Aminen, wie Diphenylamin, Thiodiphenylamin, Melamin, Hexamethylentetramin, vornimmt. Beispiel r 8,5 Teile Pentaerythrit, 5 Teile i, 4-B.utylenglykol, 31 Teile Bernsteinsäure und 1,5 Teile T iodiphenylamin werden unter Rühren bei 16o° erhitzt. Nach 2 Stunden wird die entstandene dickflüssige Masse in flache Schalen gegossen, wo sie nach kurzer Zeit zu einem linoxynähnlichen Körper erstarrt. Beispie12 5o Teile Pentaerythrit, .4o Teile t, 4-Butylenglykol, 18 Teile Äthylenglykol, 12 Teile Melamin und io8 Teile Bernsteinsäure werden unter Rühren 3 Stunden auf 16o° erhitzt. Wenn die Masse dickflüssig geworden ist, läßt man sie ausfließen und in einer Schichthöhe von ro bis 15 cm erstarren. Sie ist danach gummiartig und läßt sich wie Linoxyn verwalzen.It has now been found that pentaerythritol, divalent or trivalent Alcohols and dicarboxylic acids give linoxyn-like masses if the condensation these substances in the presence of amines, such as diphenylamine, thiodiphenylamine, melamine, Hexamethylenetetramine. Example r 8.5 parts of pentaerythritol, 5 parts of 1,4-butylene glycol, 31 parts of succinic acid and 1.5 parts of tiodiphenylamine are stirred at 160 ° heated. After 2 hours, the resulting viscous mass is placed in shallow bowls poured, where it solidifies after a short time to a linoxyn-like body. Example12 50 parts pentaerythritol, 40 parts t, 4-butylene glycol, 18 parts ethylene glycol, 12 Parts of melamine and 10 8 parts of succinic acid are heated to 160 ° for 3 hours with stirring heated. When the mass has become thick, it is allowed to flow out and in solidify a layer height of ro to 15 cm. It is then rubbery and leaves roll like linoxyn.
