The rheological investigation of concentrated solutions of aliphatic hyperbranched polyesters
(AHBP) in N-methyl-2-pyrrolidinon (NMP) is presented. Two series of hydroxy-functional
AHBP were synthesized using pseudo-one-step and one-step procedure. Three commercial
(Boltorn1) AHBP were also investigated. In the
examined temperature region (10–50 8C), AHBP
solutions (c 45 wt.-%) exhibited Newtonian behavior.
The same was observed for 50 and 55 wt.-%
solutions at T 40 8C. However, at T<50 8C, solutions
of AHBP of higher concentrations (50 and
55 wt.-%) showed shear thinning behavior. Values
of the flow activation energies were calculated for
all examined AHBP. The influence of the procedure
for the synthesis, concentration and temperature on
rheological behavior of AHBP solutions in NMP is
discussed.
