Claim 1

A PROCESS OF COMPOUNDING ADHESIVE COMPOSITIONS, COMPRISING: FORMING A MIXTURE CONTAINING WATER AND FINELY COMMINUTED DOUGLAS-FIR BARK MATERIAL AND AN ALKALI AND A REACTIVE ALDEHYDE SELECTED FROM THE GROUP CONSISTING OF: PARAFORMALDEHYDE, FORMALDEHYDE SOLUTION, FURFURALDEHYDE, AND HEXAMETHYLENETETRAMINE, IN WHICH REACTION MASS THE ALKALI IS SELECTED FROM THE GROUP CONSISTING OF SODIUM HYDROXIDE, AND MIXTURES OF SODIUM HYDROXIDE AND SODIUM CARBONATE, AND THE BARKTO-WATER RATIO IS FROM 1:1.5 TO 1:3, THE BARK-TO-ALKALI RATIO IS FROM 2.0:1 TO 6.6:1, AND THE BARK-TO-ALDEHYDE RATIO IS FROM 15:1 TO 40:1, CONDUCTING SAID REACTION AT TEMPERATURES BETWEEN ABOUT 180*F. AND 230*F. FOR FROM 5 MINUTES TO ABOUT 60 MINUTES, COOLING SAID MASS TO BETWEEN ROOM TEMPERATURE AND ABOUT 150*F., AND ADMIXING WITH THE COOLED MASS A PHENOL-ALDEHYDE THERMOSETTING RESIN, SAID RESIN BEING THE ALKALINE HIGHLY ADVANCED, HEAT FUSIBLE, ETHANOL-INSOLUBLE, WATER SOLUBLE REACTION PRODUCT OF A PHENOL AND AN ALDEHYDE HEAT REACTED AT A MOLAR RATIO BETWEEN 1:1 AND 1:3 IN THE PRESENCE OF ALKALI METAL HYDROXIDE AND HAVING AN ALKALI-TO-RESIN SOLIDS RATIO FROM ABOUT 1:4 TO 1:10, AND COOLING THE ADHESIVE COMPOSITION THUS COMPOUNDED TO NORMAL ADHESIVE TEMPERATURES.
