摘要:
An aqueous viscoelastic composition is provided comprising at least one viscoelastic surfactant, and at least one hydrophobically modified polymer, which is formed from polymerization of ethylenically unsaturated monomers; has a number average molecular weight of from 1,000 to 100,000 Da; and to a level of at least 0.1 mole %, based on the amount of monomer units in the polymer, contains monomeric units each covalently bonded to a pendant, optionally alkoxylated, hydrocarbyl group having from 6 to 40 carbon atoms, said pendant, optionally alkoxylated, hydrocarbyl group being connected to the backbone of said hydrophobically modified polymer via a non-ester containing linking group.
摘要:
The present invention generally relates to controlling the viscosity of water-based mud systems. More particularly, the present invention relates to methods and compositions for thinning and deflocculating aqueous based fluids used in well drilling and other well operations in subterranean formations, especially subterranean formations containing oil and/or gas. The invention also relates to a drilling fluid thinner and/or dispersant having improved temperature stability, dispersing properties and “solids contamination” tolerance.
摘要:
A film-forming composition includes a blend of polyvinyl alcohol and hydrophobically modified solution polymer or a water soluble polymer including an anionic ethylenically unsaturated monomer wherein the composition has a pH of about 5 or less. Further included are self-supporting materials, such as films, derived from the compositions and formulations including at least one volume-filling formulation surrounded by the self-supporting material.
摘要:
A method of inhibiting carbonate scale in an industrial water system includes the steps of dosing the industrial water system with a water treatment polymer comprising at least 60 mol % of carboxylic acid monomer and a quaternized naphthalimide fluorescent monomer as disclosed herein, and then monitoring the fluorescence of the water system. If both maleic acid and phosphino moieties are included in the water treatment polymer, then the maleic acid is present as no greater than 70 mol % of the water treatment polymer. If the polymer contains a sulfonic acid monomer, the polymer is a fluorescence efficient polymer.

摘要:
A detergent composition comprising 10 to 60 wt % detergent surfactant and 0.1 to 10 wt % of a soil release agent comprising a water soluble addition polymer having a backbone prepared from (meth)acrylic, vinylic and/or (meth)acrylamido and pendent di- and/or tri-styryl groups attached thereto.
