Appeal No. 2004-1829
Application No. 09/887,273
methylene groups and at least two branches of different lengths
containing less than 6 carbon atoms each. Further details of
this appealed subject matter are recited in representative claim
563 reproduced below:
563. A process for the production of a
polyolefin having at least 50 branches per 1000
methylene groups and at least two branches of
different lengths containing less than 6 carbon atoms
each, comprising the step of polymerizing one or more
monomers of the formula H2C=CH(CH2)eG wherein
G is hydrogen or -CO2R1,
e is 0 or an integer of 1 to 20,
R1 is hydrogen, hydrocarbyl or substituted
hydrocarbyl, and
in at least 50 mole percent of said monomers G is
hydrogen,
by contacting said one or more monomers with a
transition metal containing coordination
polymerization catalyst under polymerizing conditions
such that in said polyolefin:
(i) the number of branches per 1000 methylene
groups is 90% or less than the number of theoretical
branches per 1000 methylene groups, or
(ii) the number of branches per 1000 methylene
groups is 110% or more of theoretical branches per
1000 methylene groups; or
(iii) when there should be no branches
theoretically present, said polyolefin has 50 or more
branches per 1000 methylene groups.
The examiner does not rely on any prior art to support the
rejection of the appealed claims. (Examiner’s answer mailed
Oct. 6, 2003, paper 12, page 2.)
Claims 563 through 574 on appeal stand rejected under 35
U.S.C. § 112, ¶1, as being non-enabled. (Id. at 3-9.)
