Cationic fluorinated polymer compositions and methods for treating hydrocarbon-bearing formations using the same

摘要

Fluorinated polymers having first divalent units independently represented by formula (I) or formula (II) and second divalent units containing quaternary ammonium groups. Compositions containing the fluorinated polymer and solvent, methods of treating hydrocarbon-bearing formations using these compositions, and articles treated with the fluorinated polymers are disclosed. A method of making a composition containing the fluorinated polymer is also disclosed.;

主权项

1. A fluorinated polymer comprising:
first divalent units independently represented by formula: in a range from 15 to 75 percent by weight, based on the total weight of the fluorinated polymer, and second divalent units independently represented by formula: in a range from 25 to 85 percent by weight, based on the total weight of the fluorinated polymer, wherein
Rf represents a fluoroalkyl group having from 1 to 6 carbon atoms;each R1 is independently hydrogen or methyl;W is —O—;V is alkylene;A is R and R3 are each independently alkyl having 1 to 4 carbon atoms;R2 is alkyl having 1 to 20 carbon atoms;X— is a counter anion; andn is an integer from 2 to 11.
