Resumen:
ABSTRACT: The authors report on the viscoelastic characterization
of guar hydrogels obtained through complexation
reactions with borax ions. These gels are compared
with hydrogels obtained from poly(vinyl alcohol) of different
degree of hydrolysis through complexation reactions
with congo red. The effect of the degree of hydrolysis and
both, the concentration of PVA and the concentration of
congo red, on the viscoelastic properties of the hydrogels
is analyzed. The potential use of the PVA-based hydrogels
as hydraulic fracturing liquids is discussed in relation to
the commonly used fracturing liquid based on the guar
borax system. VVC 2008 Wiley Periodicals, Inc. J Appl Polym Sci
