Study of Intrinsic Viscosity and Flow Activation Energy of Some Polymers in Different Solvents

Abstract

The intrinsic viscosity has been studied for
several polymers which are used in some
industrial applications, such as polyisobutylene of
types Oppanol B150, 200, and 250 with different
molecular weights of 2.5, 4.1 and 5.9 million
g/mole, respectively, which dissolved in crude
and gas oil. In addition three types of additives
brought from Al-Dura refinery, olefin copolymer
(OCP), {viscoples-4-677, viscoplex-215496, and
Lubrizol R 7077} which dissolved in crude oil,
and the polymers which is soluble in water such
as polyacrylamide with high molecular weight
and xanthan gum with molecular weight 3.7
million g/mole where also studied. It was found
that the intrinsic viscosity of polyisobutylene
decrease as the temperature increase in crude and
gas oil. The olefin copolymer (Viscoplex-4-677)
showed the same behavior as polyisobutylene
where it can be used as drag reduction agent. It
was noted that neutral polymers as well as
polyelectrolytes could be used as drag reduction
agent.
