Triple derivatives of polygalactomannan i.e., dialkylaminoalkyl ether-hydroxyalkyl ether - long aliphatic chain ether of polygalactomannan, are useful as thickening agents for aqueous fluids.

Hydrophilic-hydrophobic derivatives of polygalactomannans containing

Polygalactomannans containing a hydroxybutyl ether substituent and a hydrophobic substituent can be used in the fracturing of subterranean formations.

Hydrophobically modified hydroxybutyl ethers of polygalactomannan

Water-borne coating compositions are made, using as a thickening agent, a polygalactomannan having both hydrophilic and hydrophobic substituents.

Coating composition containing as thickeners polygalactomannans modified

Quaternary ammonium containing monomers, represented by the formula: ##STR1## wherein R.sub.1 is H or methyl, R.sub.2 is an alkyl group containing 6 to 22 carbon atoms, D is an alkylene group containing 1 to 4 carbon atoms, or a hydroxylalkylene group containing 2 to 4 carbon atoms and X is an anion, are polymerized to form polymers useful in hair care preparations.

Polymers made from quaternary ammonium acrylic monomers

The viscosity of aqueous fluids thickened with a tertiary amino polygalactomannan is reduced by the addition of an alkali metal or alkaline earth metal salt of hypochlorous acid, or a chlorinated isocyanurate.

Method for reducing the viscosity of aqueous fluid

Quaternary ammonium containing monomers, represented by the formula: ##STR1## wherein R.sub.1 is H or methyl, R.sub.2 is an alkyl group containing 6 to 22 carbon atoms, D is an alkylene group containing 1 to 4 carbon atoms, or a hydroxyalkylene group containing 2 to 4 carbon atoms and X is an anion, are polymerized to form polymers useful in hair care preparations.

Quaternary ammonium acrylic monomers and alcohol soluble polymers made

Dialkylaminoalkyl-hydroxyalkyl ethers of polygalactomannan are useful as thickening agents for aqueous fluids.

Tertiaryaminoalkyl-hydroxyalkyl ethers of polygalactomannans

Alkyl ethers of polygalactomannans wherein the alkyl groups contain 1 to 4 carbon atoms are further modified with long chain aliphatic epoxides wherein the long chains contain 8 to about 28 carbon atoms. The resulting derivatized polygalactomannans are particularly useful as thickening agents for aqueous systems.

Hydrophobically modified non-ionic polygalactomannan ethers

Aqueous solutions of polygalactomannans are cross-linked with the reaction product of titanium tetrachloride and a water-soluble alcohol or diol further reacted with ammonia or a water-soluble amine. Such crosslinked products are useful in fracturing solutions for secondary oil recovery or in gel explosives.

Titanium-glycol useful as crosslinking agents for polygalactomannans

Aqueous solutions of polygalactomannans are crosslinked with the reaction product of titanium tetrachloride and a water-soluble alcohol or diol. Such crosslinked products are useful in fracturing solutions for secondary oil recovery or in gel explosives.
