Dolle in Example 8. Employing the same triad analysis of the
pentad composition indicated by the C-13 NMR
spectra for the polypropylene produced in accordance with
Ewen’s Example IV (Ewen, U.S. Patent 5,036,034, col. 8, l. 15-
29; C-13 NMR spectra data reported at col. 9, Table II) and
the same formulas to calculate the average sequence length of
its isotactic and syndiotactic sequences, we calculate niso

(4) The syndio-isoblock polymers of Dolle Application
08/147,006 are described as having long isotactic and
syndiotactic sequences (Spec., p. 1, l. 1-2).
