Abstract

See full text

In one embodiment, an alkylphenol copolymer is disclosed wherein the copolymer comprises at least one alkylphenol monomer and the alkylphenol copolymer exhibits the following: an oscillation displacement Θ of greater than 0 at a temperature of −5° C. in a first oscillation temperature sweep and an oscillation displacement Θ in a second oscillation temperature sweep within 25% of the oscillation displacement Θ in the first oscillation temperature sweep at a temperature of −5° C. In a further embodiment, a petroleum composition is disclosed wherein the composition comprises a petroleum source and a macromolecular compound wherein the macromolecular compound exhibits the following: an oscillation displacement Θ of greater than 0 at a temperature of −10° C. in a first oscillation temperature sweep, and an oscillation displacement Θ in a second oscillation temperature sweep within 25% of the oscillation displacement Θ in the first oscillation temperature sweep at a temperature of −10° C.
