“…The molecular weights listed above were calculated from intrinsic viscosities at zero rate of shear, using the equation [TJ]o = KM u with K = 1.25 X 10-2 and a = 0.78 for PEO in water [Bayley and Koleske (1976)J and with K = 6A6xlO-2 and a = 0.6 for PIB in kerosene [Ram et al (1967) J; in so doing it was accepted that [7]Jo has dimensions of mass per mass. Molecular weight determinations are more difficult with PAM than with PEO and PIB.…”

“…5,21 Já para solventes orgânicos, os polímeros mais estudados são poli-isobutileno (PIB) e poliestireno (PS). [24][25][26] As estruturas moleculares destes polímeros e de algumas outras substâncias que são capazes de produzir RAH estão apresentadas na Tabela 1.…”

“…Ram, Finkelstein, and Elata [107] have showed that addition of high molecular weight polyisobutylene greatly reduced the turbulent friction in the transportation of crude oil and kerosene. The recent successful tests of polymer injection into the Alaska pipeline to increase the throughput of Alaska crude [324,325] demonstrate the pragmatic use of the drag reduction phenomenon.…”
