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

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

The viscosity of thickened aqueous solutions of water-soluble polymers is reduced by the addition of alkali metal and alkaline earth metal salts of hypochlorous acid and tertiary amines. The combination of the salt and the tertiary amine is much more efficient in speed of reduction in viscosity and in the completeness of the degradation of the polymer than the use of the metal salt alone. The process of this invention is particularly useful in fracturing of oil wells.
