Abstract
Method for reducing the pressure drop associated with a fluid subjected to a turbulent flow which comprises introducing at least one latex into said fluid, comprising: (a) a continuous aqueous phase; (b) a plurality of particles, dispersed in said continuous aqueous phase, of at least one branched (co) polymer having a branching degree {GR) ranging from 0.05 to 0.6, preferably from 0.08 to 0.5, and a weight average molecular weight (Mw) of the parent (co) polymer ranging from 100,000 Daltons to 700,000 Daltons, preferably ranging from 140,000 Daltons to 350,000 Daltons. Said method can be advantageously used in the case of a pressure drop in pipelines transporting liquid hydrocarbons such as, for example, petroleum, crude oils and refinery or petrochemical products, in particular for long distances.
