Interference 103,482
The polymerization of propylene with a catalyst
falling within the scope of count 2 is described in
examples 3 through 12 in each of Dolle’s U.S.
applications
and the German application. Accordingly, Dolle is
entitled
to the benefit of the earlier applications as to count 2.
BB. June 30, 1998 -- The APJ ordered Redeclaration Of
Interference (Paper No. 58). New Count 2 (Paper No. 58, pp.
2-4) was substituted for original Count 1. New Count 2 in-
part reads:3
Count 2
A metallocene compound used to make a catalyst
to produce (1) hemiisotactic olefin polymers or
(2) syndio-isoblock polymers having molecular chains
in which syndiotactic and isotactic sequences are
present and the sequence length is 3 to 50 monomer
units comprising the general formula:
R”(CpR )(CpR’ )MHal
n m 2
where Cp is cyclopentadienyl or a substituted
cyclopentadienyl, each R and R’ is a hydrocarbyl radical
having from 1-20 carbon atoms and is the same or
different
and is selected such that CpR’ is a sterically different
m
ring from CpR resulting in a lack of bi-lateral symmetry
n
for the compound, R” is a structural bridge imparting
stereorigidity to the compound, M is a Group 3, Group 4,
Group 5 or Group 6 metal, n is from 0 to 4, m is from 0
to 4 and Hal is a halogen;
or
3 Count 2 is reproduced in its entirety in Appendix C of
this decision.
