C. Wohlfarth, COR-EOS AND BH-EOS PARAMETERS FOR POLYMER MELTS WITH THE ERROR IN THEALL-VARIABLES METHOD, Journal of applied polymer science, 48(11), 1993, pp. 1923-1933
All the data for more than 100 polymer melts in a PVT data base were u
sed to determine best-fit characteristic parameters for two different
theoretical equations-of-state (eos): the chain-of-rotators (COR) and
the Bruce Hartmann (BH) eos. Fitting was performed by applying an erro
r in all-variables algorithm that was recently developed by Hartmann e
t al. Despite their very different theoretical basis, both equations-o
f-state led to close descriptions of the PVT surface with comparable a
verage deviations.
