  Methods, compositions, and systems that use hydrogels of graft polymers for diversion of acidic treatment fluids in subterranean formations. A method for acid diversion may comprise: applying a first acidizing treatment to a first treatment zone of a subterranean formation; introducing a hydrogel to the first treatment zone, wherein the hydrogel comprises a graft polymer that is crosslinked; and applying a second acidizing treatment to the subterranean formation, wherein the hydrogel diverts the second acidizing treatment to a second treatment zone.

  N,N'-Diallylaldardiamides (DA) were synthesized from galactaric, xylaric, and arabinaric acids, and used as cross-linkers together with xylan (X) derivatives to create new bio-based hydrogels. Birch pulp extracted xylan was derivatized to different degrees of substitution of 1-allyloxy-2-hydroxy-propyl (A) groups combined with 1-butyloxy-2-hydroxy-propyl (B) and/or hydroxypropyl (HP) groups. The hydrogels were prepared in water solution by UV induced free-radical cross-linking polymerization of derivatized xylan polymers without DA cross-linker (xylan derivative hydrogel) or in the presence of 1 or 5 wt % of DA cross-linker (DA hydrogel). Commercially available cross-linker (+)-N,N'-diallyltartardiamide (DAT) was also used. The degree of substitution (DS) of A, B, and HP groups in xylan derivatives was analyzed according to H-1 NMR spectra. The DS values for the cross-linkable A groups of the derivatized xylans were 0.4 (HPX-A), 0.2 (HPX-BA), and 0.4 (X-BA). The hydrogels were examined with FT-IR and elemental analysis which proved the cross-linking successful. Water absorption of the hydrogels was examined in deionized water. Swelling degrees up to 350% were observed. The swollen morphology of the hydrogels was assessed by scanning electron microscopy (SEM). The presence of cross-linkers in DA hydrogels had only a small impact on the water absorbency when compared to xylan derivative hydrogels but a more uniform pore structure was achieved.

  A method for preparing a specific product from a polysaccharide in which at least one hydroxyl of a saccharide unit is substituted with an ether or ester moiety. The ether or ester moiety is provided with ethenyl and/or epoxy functionality for preparing an activatable polysaccharide polymer and the activatable polysaccharide polymer with ethenyl and/or epoxy functionality is optionally reacted with an additional coupling reagent, having at least two coupling functionality for preparing polysaccharide polymer with additional activatable crosslinker. Thereafter, the activatable polysaccharide polymer or the polysaccharide polymer with an additional activatable crosslinker, is activated for crosslinking the polysaccharide polymer with another polysaccharide polymer by reacting the activatable polysaccharide polymer or polysaccharide polymer with an additional activatable crosslinker with a crosslinking initiator for crosslinking the polysaccharide polymer chains with each other, for preparing a product such as hydrogel, film, coating or membrane with polysaccharide backbone.
