Abstract
Abstract In the processing of mineral solids by the addition thereto of aqueous systems containing resinous binders to stabilize the surfaces of such mineral solids against the erosive action of wind and water, water soluble polymers formed by the polymerization of at least one monoolefinic compound through an aliphatic unsaturated group and having a molecular weight of at least 100,000 are added to the aqueous systems containing the binders in order to control the drift when such aqueous systems are applied by spraying or otherwise to such mineral solids.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
IN A PROCESS OF CONTROLLING DRIFT OF AQUEOUS EMULSIONS OF RESINOUS BINDERS CONTAINING EMULSIFIERS AND 10 TO 20 PERCENT BY WEIGHT BINDER SOLIDS IN THE SPRAY APPLICATION OF SUCH EMULSIONS TO MINERAL SOLIDS, THE IMPROVEMENT WHICH COMPRISES INCORPORATING INTO THE AQUEOUS EMULSIONS OF RESINOUS BINDER A DRIFT CONTROLLING BUT A SUBSTANTIALLY NON-VISCOSITY INCREASING AMOUNT OF A WATER SOLUBLE POLYELECTROLYTE POLYMER FORMED BY THE POLYMERIZATION OF AT LEAST ONE MONOOLEFINIC COMPOUND THROUGH AN ALIPHATIC UNSATURATED GROUP AND HAVING MOLECULAR WEIGHT OF AT LEAST 100,000, SAID POLYMER HAVING A LINEAR HYDROCARBON STRUCTURE CONTAINING IN A SIDE CHAIN A HYDROPHILIC GROUP SELECTED FROM THE CLASS CONSISTING OF CARBOXYLIC ACID, CARBOXYLIC ACID ANHYDRIDE, CARBOXYLIC ACID AMIDE, HYDROXY, PYRIDINE, PYRROLIDONE, HYDROXYALKYL ETHER, CARBOXYLIC ACID SALT GROUPS AND MIXTURES OF SAID GROUPS, AND CONSTITUTING 250 TO 500 PARTS PER MILLION BY WEIGHT OF SAID EMULSION.
