Verfahren zur Herstellung von durch besondere Härte sich auszeichnenden Kondensationprodukten aus Phenoten und Formaldehyd.
Die Erfindung bezieht sich auf die Herstellung besonders harter Kondensationsprodukte aus Phenolen und Formaldehyd. Die gemäss dem vorliegenden Verfahren hergestellten Produkte eignen sich besonders gut zur Herstellung von Schallwalzen und Druckplatten, elektrischen

Vorliegende Erfindung besteht nun in der Verwendung gewisser Stoffe, welche im Ver- gleiche zu den bisher benutzten viel wirksamer sind, da durch ihre Verwendung Produkte er- halten werden, welche in der Kälte härter sind und unter Anwendung von Hitze und Druck leichter geformt, geprägt oder sonst bearbeitet werden können, als die bisherigen. Solche Stoffe sind die huheren Halogensubstitutionsprodukte der Phenole, beispielsweise PentachlorpMenol bzw. ihre Homologen und Derivate.
These Verbindungen, im besonderen die höheren Substitutionsprodukte, haben die Eigen- schaft, freies Ammoniak unter Bildung fester, in Wasser praktische unlöslicher Körper zu binden.
Dies ist besonders vorteilhaft, wenn das Endprodukt durch Behandlung des löslichen Phenolharzes mit Hexamethylentetramin hergestellt werden soll.
Es ist nicht erforderlich, ein bestimmtes reines Chlorderivat zu benutzen, immerhin ist

Process for the production of condensation products from phenotes and formaldehyde, which are characterized by particular hardness.
The invention relates to the production of particularly hard condensation products from phenols and formaldehyde. The products produced according to the present process are particularly suitable for the production of sonic rollers and printing plates, electrical
EMI1.1
The present invention consists in the use of certain substances which are much more effective compared to those previously used, since their use results in products which are harder in the cold and which are more easily shaped or embossed with the application of heat and pressure or can be edited otherwise than the previous ones. Such substances are the higher halogen substitution products of the phenols, for example pentachloropenol or their homologues and derivatives.
These compounds, especially the higher substitution products, have the property of binding free ammonia with the formation of solid bodies which are practically insoluble in water.
This is particularly advantageous when the end product is to be made by treating the soluble phenolic resin with hexamethylenetetramine.
It is not necessary to use any particular pure chlorine derivative, after all it is

previously distilled or sublimed. In this case the distillate or sublimate is used or a part can be distilled or sub! and only the pitch-like residue can be used. If cresol is used instead of phenol, it is recommended. Tetrachloride cresol
EMI1.3
It is also possible to prevent halogenated phenols with bases, with the exception of ammonia as additives. If formaldehyde or its polymers are used as a heating agent instead of hexamethylenetetramine, one can do this before the final hardening reaction

20 parts of pentachlorophenol, 4 parts of naphthalene, 20 parts of wood pulp, 2 parts of lamp black.
This mixture can be mucked through heated machines which are just hot enough. to keep the mass dough-like so that it cannot harden. A treatment of around 15 minutes is sufficient to bring the product to its final state
