| titleOfInvention |
Copolymer for inhibiting inorganic deposits |
| abstract |
The invention relates to a copolymer comprising: A) at least one monomer unit a) derived from at least one ethylenically unsaturated aliphatic monocarboxylic or polycarboxylic acid, from a corresponding anhydride or from a corresponding water-soluble salt; B) at least one monomer unit b) derived from a particular sulphonated or sulphated, ethylenically unsaturated ether or at least one monomer unit (b1) derived from an ethylenically unsaturated sulphonated monomer, other than (b); C) at least one monomer unit (c) derived from a monomer of average general formula [CH2=CH-CH2-R6-O-]XP(=O)(OM)3-X. The invention also relates to a method for preparing such a copolymer, to an inhibitory composition comprising such a copolymer and to a method for inhibiting inorganic deposits in an oil reservoir by means of said inhibitory composition. |
