Abstract
A wellbore fluid treatment may include a compound formed from reaction between cyclic anyhydride pendant groups on a polymer backbone with at least one amino acid, neutralized with a nitrogen containing compound. Methods may include injecting such a compound into a hydrogen production stream. Other methods may include reacting polybutadiene grafted maleic anhydride with at least one amino acid to produce an intermediate; and reacting the intermediate with an amide, amine, or imidazoline having at least a C4-C24 group to produce a compound.
