Abstract

FLOW OF A STREAM COMPRISED OF HYDROCARBONS IS IMPROVED BY INTRQDUCING INTO THE STREAM A STABLE, NON-AGGLOMERATING SUSPENSION COMPRISING:(a) WATER,(B) HIGHLY DISPERSED IN THE WATER, AND SUBSTANTIALLY INSOIUBLE THEREIN, AND EXTREMELY FINELY-DIVIDED, NON-CRYSTALLINE, ULTRA-HIGH MOLECULAR WEIGHT, HYDROCARBON-SOLUBLE, UNDEGRADED POLYALKENE HAVING 2 TO ABOUT 30 CARBON ATOMS PER ALKENE PRECURSOR AND AN INHERENT VISCOSITY OF AT LEAST 20 DL/G, AND(C) A SMALL BUT EFFECTIVE AMOUNT OF A SURFACTANT HAVING A HLB OF AT LEAST ABOUT 9. THE FINELY DIVIDED POLYALKENE IS PREPARED BY POLYMERIZATION AND THEN CRYOGRINDING BELOW THE GLASS TRANSITION TEMPERATURE OF THE POLYALKENE.
