Abstract

Water-soluble thermosettable phenol-formaldehyde resins are obtained by (a) reacting 1 mole phenol with 2.2 to 3.5 moles formaldehyde in water in the presence of 0.15 to 0.6 hydroxyl equivalents of an alkali or alkaline earth metal oxide, hydroxide or salt of an acid of dissociation constant not more than 1.1 x 10-2 at 100 DEG to 165 DEG F. until a free formaldehyde level within 10% of the minimum is attained, and (b) rapidly cooling to about room temperature. The rosins may be used to impregnate wood or paper, especially to impregnate cellulose paper for use as battery separators in which case the resin is freed from metal ions, e.g. by means of an ion-exchanger or filtration of insoluble metal salts.ALSO:Water-soluble thermo-settable phenol-formaldehyde resins for impregnating wood or paper are obtained by reacting 1 mole of phenol with 2.2 to 3.5 moles formaldehyde in aqueous medium in the presence of 0.15 to 0.6 hydroxyl equivalents of an alkali or alkaline earth metal oxide, hydroxide or salt of an acid of dissociation constant not above 1.1 x 10-2 at 100 DEG to 165 DEG F. until a free formaldehyde level within 10% of the minimum is attained and then rapidly cooling to about room temperature. The resins are particularly suitable for impregnating cellulose paper to form battery separators in which case the resin is first freed from metal ions.
