Abstract

A resinous body prepared by condensing an aliphatic or aromatic ketone, such as acetone,aand an aldehyde, such as formaldehyde, by treatment with an alkali, is produced in presence of a pulverulent substance such as ground wood, peat, straw, paper, asbestos, or metal. After removal of excess alkali and moisture, the powder is pressed or stamped into any desired form at pressures of 150-500 atmospheres and temperatures of 120-200 DEG C. Fillers such as cement, graphite, talc, kaolin, heavy spar, lithopone, glass powder &c. may be used with the materials before condensation, or elastic and insulating properties may be obtained by the addition of oils, waxes, rubber resin or other natural or artificial resins, shellac, cellulose esters, ebonite, haemoglobin, &c. either before or after the condensation. As condensing-agents ammonia, alkaline hydroxides, carbonates, or sulphides, or alkaline earth hydroxides may be used. The aldehyde may be replaced by its polymers, by hexamethylenetetramine, or by substances which liberate formaldehyde.
