Table II using Winter’s Equation (I) is 3.6. The correct
fraction for the pentad rmmr reported in Randall’s Table II
is 0.037, not the 0.087 fraction Dr. Gauthier used for his
calculations (RE 33; RE 46). Nevertheless, Randall
acknowledges that the fractions reported in Table II for the
pentads mmrm and rmrr, based on the C-13 NMR spectrum of the
particular amorphous polypropylene analyzed, have been
questioned because of poor resolution and overlap of the
corresponding peaks of the C-13 NMR spectrum of Figure 1 (see
footnote d to Randall’s Table II and Figure 1 itself).
Accordingly, the evidence to which Dr. Gauthier points in
support of his beliefs is questionable.
Even if we assume, however, that Randall’s Table II does
describe an amorphous polypropylene having molecular chains in
which syndiotactic and isotactic sequences are present and the
average sequence length is 3 to 50 monomer units when
calculated by Winter’s formulas (I) and (II), we fail to see
how this evidence shows that the APJ erred in interpreting the
term “sequence length” in light of Dolle’s specification to
mean “average sequence length”. Even if we were to find that
syndio-isoblock polymers having molecular chains in which
syndiotactic and isotactic sequences are present and the
