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 100 ml of said organic liquid, wherein the polymeric complex is the reaction product of a metal neutralized sulfonated octene-1/ethylene/ethylidene norborene terpolymer and a basic nitrogen-containing copolymer, said basic nitrogen containing copolymer being a copolymer of vinylpyridine with another monomer selected from the group consisting of styrene, t-butyl styrene, alkylacrylate, alkylmethacrylate, butadiene, isoprene, vinyl chloride and acrylonitrile.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. 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 100 ml of said organic liquid, wherein the polymeric complex is the reaction product of a metal neutralized sulfonated octene-1/ethylene/ethylidene norborene terpolymer and a basic nitrogencontaining copolymer, said basic nitrogen containing copolymer being a copolymer of vinylpyridine with another monomer selected from the group consisting of styrene, t-butyl styrene, alkylacrylate, alkylmethacrylate, butadiene, isoprene, vinyl chloride and acrylonitrile.
2. A method according to claim 1 wherein said styrene/vinylpyridine copolymer contains about 0.5 to about 50 mole percent of vinylpyridine.
3. A method according to claim 1 wherein said sulfonated polymer is in excess of said basic nitrogen containing polymer.
4. A method according to claim 1 wherein said basic nitrogen containing polymer is in excess of said sulfonated terpolymer.Cited by (0)
