  This is the last part of a series of five articles published in Journal of
Rheology (Maier et al. (1998), Thimm et al. (1999a), Thimm et al. (2000a),
Thimm et al. (2000c)) in which progress on the determination of binary
molecular weight distributions from rheological data has been reported. In this
article is discussed in how far the developed methods can also be used to
characterize long-chain branching effects.
  Monomodal samples which contain long-chain branches will show two relaxation
processes in the rheological examination, which are converted to two peaks in a
corresponding molecular weight distribution. But these samples will show only
one peak in a molecular weight distribution determined by a size-exclusion
chromatography examination. This difference can be used to characterize
long-chain branched materials as will be explained in this article.
  The usefulness of this method is demonstrated by examining polymers, which
contain definite long-chain branches specified from the way, they were made.
