A method of preparing Polymers useful in Recovery and Treatment of Natural Wealth.

摘要

Method for preparing polymer of N - Vinyl - lactams, including homopolymers, copolymers and termopolimeros.Is Polymerized by Free radical initiation by the monomer and, Optionally, an unsaturated amide as monomer and, Optionally, up to about 10% by weight of at least one termonomero through polymerization of Aqueous Type Selected, generally, C Contains Salt electrolyte Mixed Alkaline Earth Metal,At least one Tertiary alkanol and an at least partially polymerization initiated by the introduction of electromagnetic radiation or nuclear. Application in the Recovery of Natural Resources, such as Oil Recovery, Drilling, workover and well completion.
