Reduction of aqueous fluid drag with poly(vinylamine)
- Air Products and Chemicals Inc., Allentown, PA (United States)
During the past several years, Air Products and Chemicals, Inc. has developed technology to prepare a family of water-soluble polymers containing primary amine functionality. Heretofore, such amine functional polymers (AFP`s) had been commercially unavailable. One of these AFP`s poly(vinylamine) (PVAm) has been examined as a drag reducing agent for aqueous solutions. Specifically, a protonated derivative of PVAm, PVAm-HCl (Mw: 0.8 million, excluding HCl) shows outstanding performance in comparison to well-established drag reducing polymers such as poly(ethylene oxide) and poly(acrylamide). The level of drag reduction is far above that expected based upon Mw and resistance to degradation is superior to any polymer examined. Both phenomena are explained in terms of PVAm-HCl having a high intrinsic viscosity and a relatively linear form in solution. Because of the excellent performance at low Mw and superior stability, commercial use of PVAm-HCl (and potentially other AFP`s) in aqueous fluid drag reduction may be possible.
