A method of sealing porous earthen surfaces which are in contact with ponded water which comprises treating the water in contact with such surfaces with the following composition:

Method of using admixture of water-soluble polymers in latex form and

Reduction of encrustation of a soil where tender crops are germinated by treating the seed bed with an effective amount of a quaternary ammonium cationic polymer, either polydiallyl dimethyl ammonium chloride or a polymer of dimethylamine/epichlorohydrin dissolved in water.

Soil anti-crustant

Aquatic herbicides of improved activity are afforded by applying them beneath the surface of waters that contain undesirable aquatic vegetation, said application being performed in the presence of a water-soluble vinyl addition polymer having a molecular weight of at least 10,000, and an inorganic salt cross linking agent.

Overspraying in solvent system paints is controlled by adding to the paints a fraction of a per cent of an oil soluble polymer, preferably one having a linear hydrocarbon structure derived from an ethylenically unsaturated monomer containing 2 to 5 carbon atoms.

Control of overspray in solvent system paints

Resistance to flame propagation or accidental ignition in the first place is achieved by applying to the surface in sequence, but not together, calcium chloride and sodium aluminate each in aqueous solution.
