Abstract:
THE PRESENT INVENTION RELATES TO METHODS AND COMPOSITIONS FOR REDUCING THE FRICTIONAL PRESSURE LOSS ENCOUNTERED IN THE TURBULENT FLOW OF HYDROCARBON LIQUIDS THROUGH A CONDUIT. BY THE PRESENT INVENTION A FRICTIONAL PRESSURE LOSS ADDITIVE IS INTERMIXED WITH THE HYDROCARBON LIQUID, THE ADDITIVE BEING HOMOPOLYMER OR A COPOLYMER OF ALKYL ACRYLATE AND METHACRYLATE MONOMERS HAVING ESTER GROUPS CONTAINING FROM 4 TO 18 CARBON ATOMS OR COPOLYMERS OF SUCH MONOMERS AND CERTAIN STYRENE ACRYLATE OR METHACRYLATE TYPE MONOMERS.
