Abstract
Drag reducing compositions comprising polymer particles, where the polymer particles include copolymers comprising the residues of at least one methacrylate monomer and at least one comonomer having a polymerizable vinyl group, where the comonomer has no more than one pendant substituent per vinyl carbon. The drag reducing compositions can have improved dissolution rates in hydrocarbon-containing fluids. The drag reducing compositions can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.
