Associates of inorganic metal compounds with copolymers containing a plurality of hydroxy groups

Claim 1

THE PROCESS COMPRISING COMMINGLING, IN THE PRESENCE OF A LIQUID REACTION MEDIUM CONSISTING ESSENTIALLY OF FROM 5% TO 90% OF AN ALIPHATIC OXYGEN-CONTAINING ORGANIC LIQUID, FROM 10% TO 95% BY WEIGHT OF A LIQUID HYDROCARBON WHICH IS SUBSTANTIALLY IMMISCIBLE WITH WATER AND FROM 0% UP TO THE AMOUNT COMPLETELY MISCIBLE WITH WATER SAID OXYGEN-CONTAINING LIQUID OF WATER, A METAL COMPOUND OF THE GROUP CONSISTING OF METAL HYDROXDES, METAL OXIDES, AND METAL SALTS OF WEAK ORGANIC ACIDS, IN THE FORM OF SOLID PARTICLES OF COLLOIDAL DIMENSIONS, WITH A LEAST 10% OF THE WEIGHT OF SAID LIQUID HYDROCARBON OF A HYDROLYZED COPOLYMER OF AN ALPHA HYDROCARBON OLEFIN HAVING AT LEAST 10 CARBON ATOMS, WITH A VINYL ESTER OF A FATTY ACID CONTAINING UP TO 5 CARBON ATOMS, SAID COPOLYMER HAVING A MOLECULAR WEIGHT OF FROM ABOUT 4,000 TO ABOUT 50,000, SAID HYDROLYZED COPOLYMER CONTAINING AT LEAST TWO NON-ACIDIC HYDROXYL GROUPS PER MOLECULAR UNIT AND CONTAINING FROM ABOUT 1 TO ABOUT 6 NON-ACIDIC OXYGEN-CONTAINING UNITS PER HYDROCARBON UNIT THEREIN.
