Maleic Anhydride Polymers and Methods of Treating Subterranean Formations |
| abstract |
This document relates to compositions including a maleic anhydride copolymer or a salt thereof and an amine crosslinker. The maleic anhydride copolymer includes repeat units I and II: n n n n n n n n n n Each R 1 is independently selected from the group consisting of —H, —O(C 1 -C 5 )alkyl, and —(C 1 -C 5 )alkyl. Each R 2 is independently selected from the group consisting of —H, —O(C 1 -C 5 )alkyl, and —(C 1 -C 5 )alkyl. The maleic anhydride copolymer further includes at least one hydrolyzed repeat unit selected from repeat units III and IV: |
