Abstract

Композиция, уменьшающая сопротивление течению, содержащая по меньшей мере один неполи-альфа-олефиновый полимер, характеризующийся средним размером частиц в диапазоне от приблизительно 5 до приблизительно 800 мкм. Неполи-альфа-олефиновый полимер первоначально может быть получен в результате проведения эмульсионной полимеризации. После этого первоначальные полимерные частицы могут быть, по меньшей мере, частично уплотнены, а затем измельчены и суспендированы в текучем носителе. Получающаяся в результате уменьшающая сопротивление течению композиция может быть добавлена к углеводородсодержащей текучей среде для уменьшения падения давления, связанного с турбулентным течением углеводородсодержащей текучей среды через канал.
