The present invention generally relates to methods and hydrate inhibitor compositions for inhibiting the formation of hydrates in a fluid comprising gas and water. More specifically, the method comprises contacting a hydrate inhibitor composition to a fluid. The hydrate inhibitor composition comprises a nonpolar solvent; a polar solvent; and a polymer, an oligomer, a dendrimer, or an acid or salt thereof.
