| titleOfInvention | Aqueous drag reduction with novel acrylamide-N-alkyl acrylamide copolymers |
| abstract | A method for reducing frictional drag of water in flow through pipes comprising adding about 5 to about 100 ppm of a water soluble copolymer to said water, said copolymer having the formula: ##STR1## wherein R 1 is an alkyl or cycloalkyl group having about 6 to about 22 carbon atoms, R 2 is the same or different alkyl group as R 1 or hydrogen, x is about 90.0 to about 99.9 mole %, and y is about 0.1 to about 10.0 mole %. |
