Promotor de fluxo, processo para produzir um promotor de fluxo e processo para reduzir perda de pressão associada com o fluxo turbulento de um fluido através de um duto

摘要

A flow improver comprising a plurality of core-shell particles that can be formed by emulsion polymerization. The core of the core-shell particles can include a drag reducing polymer, while the shell of the particles can include repeat units of a hydrophobic compound and an amphiphilic compound. The flow improver can demonstrate increased pumping stability over conventionally prepared latex flow improvers.
