Methods of coating seeds with polymers and seeds coated with such polymers are disclosed herein. The polymers can be phosphonates, sulfonates, polymers of ethylenically unsaturated carboxylic acids, polyaminopolyethermethylene phosphonate, polysuccinic oligomers, acrylic acid/2-acrylamido-2-methylpropane sulfonic acid, blends of acrylic acid/2-acrylamido-2-methylpropane sulfonic acid with polyaminopolyethermethylene phosphonate, sulfomethylated acrylic acid/acrylamide, blends of sulfomethylated acrylic acid/acrylamide with polyaminopolyethermethylene phosphonate, polymaleic acid, acrylic acid/acrylamide copolymers, polyacrylic acid, trimethylglycine hydrochloride, blends of polyaminopolyethermethylene phosphonate with trimethylglycine hydrochloride, and any combination or salt of such polymers. Methods of monitoring, determining, and controlling the concentration of scale inhibitors in an agricultural irrigation system are also disclosed herein.

Polymers useful in agricultural applications

The present disclosure is directed to compositions and methods that may be used for enhanced oil recovery, for modifying the permeability of subterranean formations and for increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations. The compositions may include, for example, expandable cross linked polymeric microparticles having an unexpanded volume average particle size diameter of from about 0.05 to about 5,000 microns and a cross linking agent content of from about 100 to about 200,000 ppm of hydrolytically labile silyl ester or silyl ether crosslinkers and from 0 to about 300 ppm of non-labile crosslinkers.

Compositions and methods for diverting injected fluids to achieve improved hydrocarbon fluid recovery

An antimicrobial composition prepared by mixing a polymer-ammonium salt formulation comprising one or more polymers and one or more ammonium salts with alkali and a chlorine source in a molar ratio of chlorine (as Cl) to ammonium ion of about 1:10 to about 10:1 and methods of using the composition to control biofouling of aqueous systems.

Antimicrobial composition

A high molecular weight, water-soluble polymer comprising pendant salicylic acid groups and having a weight average molecular weight of at least about 2,000,000 daltons and use of the polymer for clarifying red mud-containing liquors generated in the Bayer process for the recovery of alumina from bauxite.

High molecular weight polymers containing pendant salicylic acid groups for clarifying bayer process liquors

This invention is directed to a composition comprising encapsulated expandable polymeric microparticles including expandable base microparticles encapsulated in a shell of at least one layer of a labile or degradable encapsulation material. The encapsulated microparticles have an unexpanded volume average particle size diameter of from about 0.05 to about 5,000 microns. The invention is further directed to the use of the composition for modifying the permeability of subterranean formations and increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.

A dispersant system useful in the formation of dispersions of water soluble polymers is disclosed. The dispersant system comprises two polymers, the first being a copolymer of diallyldimethyl ammonium chloride with a C.sub.6 to C.sub.20 quaternary ammonium salt of a monomer selected the from the group consisting of dialkylaminoalkylacrylates, dialkylaminoalkylmethacrylates, dialkylaminoalkylacrylamides, and dialkylaminoalky (meth) acrylamides as well as certain alkyl esters of acrylic acid. The second polymer is a water soluble cationic polymer composed of at least 20 mole percent of a cationic monomer represented by the formula: ##STR1## where R.sub.4 is either hydrogen or CH.sub.3 ; R.sub.5 and R.sub.6 are each an alkyl group having 1 to 2 carbon atoms; R.sub.7 is a hydrogen atom or an alkyl group having 1 to 2 carbon atoms; A.sub.2 is either an oxygen atom or NH; B.sub.2 is either an alkylene group having 2 to 4 carbon atoms or a hydroxypropylene group and X.sub.2.sup.- is an anionic counterion.
