Complexes of bentonite, polyamine and monoquaternary ammonium compounds

Claim 1

A BENTONITE COMPLEX CONSISTING ESSENTIALLY OF THE REACTION PRODUCT OF BENTONITE AND (A) A POLYAMINE CONTAINING AT LEAST 2 AMINO GROUPS WHICH ARE SUFFICIENTLY BASIC TO FORM ACETATE SALTS, SAID POLYAMINE BEING THE REACTION PRODUCT OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF AMMONIA AND ALKYL AMINES WITH A DIHALIDE SELECTED FROM THE GROUP CONSISTING OF DIHALIDES IN WHICH THE HALOGEN ATOMS ARE SEPARATED BY AN ALKYLENE GROUP CONTAINING FROM 2 TO 6 CARBON ATOMS AND DIHALIDES IN WHICH THE HALOGEN ATOMS ARE SEPARATED BY A POLYOXYALKYLENE GROUP CONTAINING FROM 2 TO 6 RECURRING UNITS, EACH ALKYLENE GROUP CONTAINING FROM 2 TO 6 CARBON ATOMS AND (B) A QUATERNARY AMMONIUM COMPOUND HAVING TWO ALKYL GROUPS ATTACHED TO THE NITROGEN ATOMS, EACH OF SAID ALKYL GROUPS CONTAINING FROM 8 TO 22 CARBON ATOMS, SAID NITROGEN ATOMS ALSO BEING SUBSTITUTED WITH TWO ALKYL GROUPS CONTAINING FROM 1 TO 4 CARBON ATOMS, THE QUANTITY OF (A) BEING LESS THAN ONE EQUIVALENT PER 10 EQUIVALENTS OF (B) BUT SUFFICIENT TO MATERIALLY STIFFEN A GREASE MADE FROM SAID COMPLEX, THE TOTAL QUANTITY OF (A) AND (B) BEING SUCH THAT ESSENTIALLY ALL OF THE EXCHANGEABLE METAL CATION IN THE BENTONITE IS REPLACED BY THE CATIONS OF (A) AND (B).
