摘要: An amphoteric water-in-oil self-inverting polymer emulsion is prepared which contains a copolymer of (1) nonionic vinyl monomer and (2) an or terpolymer monomer, anionic (3) cationic in the aqueous phase, hydrocarbon oil for emulsifying agent inverting surfactant. example such as acrylamide methacrylamide reaction product dimethylaminoethyl methacrylate monochloroacetic acid. methacrylamide, sodium acrylate triethyl ammonium ethyl methosulfate salt. The useful papermaking, treatment sewage industrial wastes, drilling muds secondary tertiary recovery petroleum by water flooding.
