Abstract

326,214. Groves, W. W., (I. G. Farbenindustrie Akt.-Ges. Oct. 1, 1928. Divided on and addition to 298,085, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 1, 1928. Phenol-aldehyde condensation products containing carboxylic groups formed by reacting a phenolformaldehyde resin with a halogen-fatty acid or by reacting a phenoxy-fatty acid with formaldehyde are hardened bv heating to above 100‹ C. with a polyhydric alcohol, with or without a filling material. For example the resin is dissolved in alcohol, a polyhydric alcohol, such as glycerine or pentaerythritol is added, and the whole is evaporated and heated as above described; or the resin may be simply mixed with the polyhydric alcohol and heated. In the examples, (1) Bakelite A is reacted with chloracetic acid as described in Example 1 of the parent Specification, the resin-carboxylic acid is dissolved in alcohol, and 'glycerine is added, the mixture being kneaded with paper pulp; (2) cresol and formaldehyde are condensed in presence of alkali, and the reaction mass is treated with more alkali and sodium chloracetate; the resin-carboxylic acid is precipitated by hydrochloric acid, dissolved in alcohol, and polyvinyl alcohol is added, the mixture being evaporated and the residue heated to 150-170‹ C.
