Polymer compositions useful as flow improvers in cold fluids |
| 摘要 |
A drag-reducing polymer capable of dissolving even in cold fluids is described, along with a method for manufacturing said drag-reducing polymer. The drag-reducing polymer has at least one alpha-olefin monomer with between a four and nine carbon chain length and a co-monomer and has less than 25% monomers (molar content) with carbon chain lengths of 12 or longer. A drag-reducing polymer suspension is also described.
