ABSTRACT:
New copolymers soluble in water and aqueous acids are disclosed comprising in a statistical distribution in the macromolecule at least 5% by weight of entities containing a formylamino functionality and at least 10% by weight of entities containing an amino carbonyl functionality, which are stable in high concentrations of Bronsted-Lowery acids and can be used as friction reducers in the stimulation of oil or gas wells.
