Abstract
Resinous adhesive masses are obtained by reacting at reflux temperatures a molten mixture of a methylol monohydric phenol and a polyhydric phenol having its hydroxyl groups on the same aromatic nucleous. The methylol phenol may be used in proportions sufficient to give a one-stage resin or a two-stage resin hardenable by addition of a setting agent. There are specified: polyhydric phenols: resorcinol, catechol, hydroquinone, pyrogallol, phloroglucinol; methylol monohydric phenols: phenol, cresol, cresylic acid, or xylenols substituted by one or more methylol groups. As setting agents for the two-stage resins are specified: hexa, oxymethylenes, paraform, paraldehydes, methylol compounds, e.g. dimethylol paracresol, methylol ureas or thioureas or methylol-melamines, with or without hexa, acetaldehyde, paraldehyde, propionaldehyde, butyl aldehydes, or furfuraldehydes. Catalysts for the reaction may be oxalic, hydrochloric, sulphuric, phosphoric, boric, citric, salicylic or acetic acids, or borax, sodium hydroxide, azoxy-toluidine, aniline, or ethanolamines. Alcohols and aliphatic and aromatic ketones are specified as solvents. The products may be used to bond laminates in forming aeroplanes, furniture, boats, and laminations of wood, metal, or alternate layers of wood and cloth or asbestos may be used. A polymethylol phenol for use as a setting agent is prepared by reacting phenol and formaldehyde at 20-25 DEG C. with a sodium hydroxide catalyst. The Specification as open to inspection under Sect. 91 describes the reaction of mono- and poly-hydric-phenols with other methylol compounds, e.g. resorcinol and dimethylol urea, nitromethane, or trimethylol amino methane; phenol and dimethylol urea. A fusible resin is obtained by reacting resorcinol at 100 DEG C. with part of the formaldehyde and adding the remainder while keeping the mixture boiling. Trimethylol methane is specified as hardener. This subject-matter does not appear in the Specification as accepted.
