hemiisotactic olefin polymers in Ewen, U.S. Patent 5,036,034
(Appendix F). However, as structurally defined in Ewen, U.S.
Patent 5,036,034 (col. 1, l. 52, to col. 2, l. 22, and col. 4,
l. 15-38), hemiisotactic olefin polymers, eg., polymers with
mmrrmm configurations, are not likely to be syndio-isoblock
olefin polymers having molecular chains in which syndiotactic
and isotactic sequences are present and the average sequence
length is 3 to 50 monomer units. See Ewen, U.S. Patent
5,036,034,
col. 1, l. 52, to col. 2, l. 22, and col. 4, l. 15-38.
(3) The syndio-isoblock polypropylene polymers having
molecular chains in which syndiotactic and isotactic sequences
are present and the sequence length is 3 to 50 monomer units
which Dolle exemplifies in Application 08/147,006 and produced
by polymerizing propylene with a metallocene catalyst
purportedly representative of the metallocene catalysts Dolle
generically describes, reasonably appear to be patentably
indistinct from the hemiisotactic polypropylene polymer Ewen
exemplifies in U.S. Patent 5,036,034 and produced by
polymerizing propylene with
a metallocene catalyst purportedly representative of the
metallocene catalysts Ewen generically describes. Compare
