Abstract

284,589. Soc. of Chemical Industry in Basle. Jan. 29. 1927, [Convention date]. Samples furnished. Moulding formaldehyde-amine condensation products.-Homogeneous masses are obtained from condensation products of an aromatic amine and formaldehyde by subjecting the products, after suitable pretreatment, to compression. The pressure applied may be 160 atmospheres at 150‹ C. or 30-50 atmospheres at 100‹ C., or alternatively the product may be pressed cold, for example at 160 atmospheres, and may then he hardened subsequently at a raised temperature.
