ABSTRACT:
A method for reducing the frictional drag of an organic liquid in flow through pipes or conduits having a continuous bore therethrough which comprises adding about 0.001 to about 0.5 grams of a polymeric complex to said organic liquid, wherein the polymeric complex is the reaction product of a copolymer containing an alpha-olefin and vinyl alkylenecarboxylic acid and a basic nitrogen-containing compolymer, wherein said acid copolymer of alpha-olefin and vinyl alkylenecarboxylic acid has the formula: ##STR1## wherein R.sub.1 is an alkyl group having 1 to 25 carbon atoms, Z is an alkyl group having about 1 to about 25 carbon atoms, R.sub.2 is an alkylene group having about 3 to about 17 carbon atoms, x is about 95.0 to about 99.99 mole % and y is about 5.0 to about 0.01 mole % and z is about 0.01 to about 5.0 mole percent, said basic nitrogen containing polymer being a copolymer of vinyl pyridene with another monomer selected from the group consisting of styrene, t-butyl styrene, alkylacrylate, alkyl methacrylate butadiene, isoprene, vinyl chloride and acrylonitrile.
