Oligomeric and polymeric electronically-modified boronic acids and methods of using the same

A method comprising:

• providing a treatment fluid that comprises:
• an aqueous base fluid;
• a gelling agent;
• a polymer comprising:
• a monomer unit M1 comprising a boronic acid;
• and
• an optional comonomer;
• wherein the boronic acid comprises a structure of Formula I:
• wherein X1 and X2 are independently selected from the group consisting of O, CH2, CH2O, OCH2, bond, and null;
• Y1 and Y2 are independently N or C;
• Ar is a 5- or 6-membered ring aryl or heteroaryl group with a link L to monomer unit M1;
• m is 1 or 2;
• n is 0, 1, 2, or 3;
• and
• each incidence of Z is independently an electron withdrawing group selected from the group consisting of nitro, ester, carboxylic acids, carboxylates, halogen, cyano, amide, acyl, alkylsulfonyl, arylsulfonyl, heteroarylsulfonyl, CF3, a quaternary ammonium salt, polyhaloalkyl, and carbamate;
• with the proviso that when n is 0, the link L between M1 and Ar comprises an electron withdrawing group attached to Ar;
• and
• introducing the treatment fluid into a subterranean formation at a pressure sufficient to create or enhance at least one fracture therein.
