Novel polymer for drag reduction in hydrocarbon fluids is dis- closed which comprises polymerising a C-12 to C-18 acrylate or methacrylate monomer and an ionic with or without other monomers acting as fillers or additives at a temperature between 20 and 30°C with constant stirring and separating the resultant polymer. The preparation of the polymers is simple, shear stability is good even at high shear rates, insensitivity to the presence of any other polar solvent and good solubility in almost all the hydrocarbon liquids. The novel polymer reduces friction in the flow of a hydrocarbon fluid by a factor around 5 at concentra- tions as low as 1 to 25 ppm.
