Abstract: 247,957. Bakelite Ges. Feb. 17, 1925, [Convention date]. Phenol-aldehyde condensation products. - Porous substances containing phenol-aldehyde condensation products or compositions containing these products and filling agents are made by dissolving the condensation products in alkali or salt solutions or mixtures of the same, in the presence or absence of organic solvents, impregnating the porous substances or filling agents with the solution, and precipitating the condensation product in the presence of the said substances or agents. The solution of the condensation product may also be mixed with solutions from which a filling ingredient is thrown down bv the precipitant. Thus calcium salts may be added, from which gypsum is precipitated by sulphuric acid, or viscose may be added to deposit cellulose. Solutions or mixtures, e.g. glue, gum arabic, tannin, or tanning agents, which in part form both precipitant and filling agent, may also be used. The precipitation of the condensation product may be effected by acids in the presence of solutions of hydrotropic salts, or by means of salts without acids, or by water. In examples, wood flour and paper pulp are mixed with an alkaline solution of a phenol-aldehyde condensation resin and the resin is precipitated by adding aluminium sulphate solution. Paper, leather, hides, skins, textile materials, or wood, or articles made of these materials, e.g. paper webs, stencils, string, ropse or nets, may be impregnated or coated with the alkaline, resin solution, and precipitation effected in or upon the materials bv means or dilute acids, salts and the like. The materials may also be stored in an atmosphere of carbon dioxide, or left exposed to the air. in which case the carbon dioxide acts to precipitate the resin. The process mav also be carried out bv impregnating the materials with the precipitant and then adding the solution of the resin. Reference has been directed by the Comptroller to Specification 28155/10.
