| titleOfInvention |
Relative permeability modifiers based on hydrophobically modified cationic copolymers |
| abstract |
Copolymers of acrylamide or methacrylamide, suitably modified with appropriate percentages of units deriving from comonomers of a hydrophobic nature and comonomers containing a positively charged ionic group, which are capable of effectively reducing the water permeability of a porous medium. |
