Biodegradable modified polyaspartic polymers for corrosion and scale control |
| 摘要 |
Several copolymers of aspartic acid and another monomer provide effective mild steel corrosion inhibitors and scale formation inhibitors under oil field conditions. The copolymers are polymers of modified polyaspartic acid mer units and polyaspartic acid mer units. The resulting polymers are biodegradable.
