Preparation and properties of a double quaternary ammonium copolymer used in acid fracturing

Triethylamine (TEA), 1, 4-dibromobutane (C4H8Br2) and N, N-dimethylaminopropyl acrylamide (DMAPAA) were selected to synthesize a double quaternary ammonium cationic monomer (TDD). TDD, acrylamide (AM), 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and acrylic acid (AA) were used to create a quad...
