Claim 1
Independent Claim
130 words
AN IMPROVED PROCESS FOR SULUBILIZING AN ACIDIC POLYMER PREPARED BY POLYMERIZING AN ACIDIC MONOMER CONTAINING AT LEAST ONE ACID GROUP PER MOLECULE WITH COPOLYMERIZABLE MATERIAL COMPRISING A CONJUGATED DIENE CONTAINING 4 TO 6 CARBON ATOMS PER MOLECULE, THE RATIO OF CARBON ATOMS TO ACID GROUP IN SAID ACIDIC POLYMER BEING NOT GREATER THAN 25:1, WHICH PROCESS CONSISTS OF MILLING INTO AN UNCOMMINUTED MASS OF SAID ACIDIC POLYMER, UNDER ESSENTIALLY ANHYDROUS CONSITIONS, A BASIC COMPOUND CAPABLE AND CAPABLE OF ENVOLVING CARBON DIOXIDE ACIDIC POLYMER AND CAPABLE OF ENVOLING CARBON DIOXIDE WHEN THE RESULTING MIXTURE IS CONTACTED WITH WATER, SAID BASIC COMPOUND BEING EMPLOYED IN AN AMOUNT SUFFICIENT TO CAUSE SAID CARBON DIOXIDE TO EFFECT MECHANICAL SHREDDING AND TUNNELING OF SAID RESULTING MIXTURE WHEN THE SAME IS CONTACTED WITH AN AQUEOUS SOLVENT.
