Abstract
Abstract AMINE SALTS OF PHENOPLASTS CARRYING CARBOXYLIC GROUPS PREPARED BY: (A) ETHERIFYING HEAT-CURABLE PHENOL-ALDEHYDE CONDENSATION PRODUCTS, SUCH AS MONONUCLEAR AND POLY-NUCLEAR PHENOLS CONDENSED WITH ALDEHYDES AND PAR-TIALLY ETHERIFIED WITH LOWER MONOHYDRIC ALIPHATIC ALCOHOLS HAVING 1 TO 4 C-ATOMS, BY WARMI. G WITH ALIPHATIC MONO- OR DIHYDROXY CARBOXYLIC ACIDS HAVING 2 TO 20 C-ATOMS OR THEIR ESTERS WITH ALCOHOLS HAVING 1 TO 6 C-ATOMS; (B) SAPONIFYING THE CONDESNATES HAVING ESTER GROUPINGS IN AN ALKALINE MEDIUM; (C) SEPARATING THE ETHERIFIED PHENOLIC RESIN-CARBOXYLIC ACID; AND (D) MIXING THE SEPARATED PHENOLIC RESIN-CARBOXYLIC ACID WITH AMMONIA AND/OR STRONG ORGANIC NITROGEN BASES.
