Abstract
This document relates to compositions including a crosslinkable polymer including a pendant epoxide repeat unit and an amine crosslinker, and methods of treating a subterranean formation by providing the composition to the formation. The pendant epoxide repeat unit has the structure Each R1 is independently a (C1-C10) alkylene or (C1-C10) alkylene ether, each alkylene ether independently having a ratio of carbon atoms to oxygen atoms of 1:1 to 4:1.
