Appeal No. 2007-0111
Reexamination 90/006,297
1 mixtures of atactic, partially isotactic and highly isotactic
2 homopolymers of the of the unsaturated hydrocarbon,
3 polymerizates comprising linear, regular head-to-tail
4 copolymers of said hydrocarbons with each other, and
5 polymerizates comprising linear, regular head-to-tail
6 copolymers of said unsaturated hydrocarbons with
7 ethylene in which said unsaturated hydrocarbon
8 predominates in the copolymer molecule, which
9 comprises the steps of (a) reacting a halide of a heavy
10 metal selected from the group consisting of titanium,
11 zirconium, hafnium, thorium, vanadium, tantalum,
12 niobium, chromium, molybdenum, tungsten and uranium
13 with a metallorganic compound of a metal selected from
14 the group consisting of beryllium, magnesium, zinc,
15 cadmium, boron and aluminum in an inert hydrocarbon
16 solvent, in the absence of air, (b) introducing said
17 material to be polymerized into the reaction product of
18 the heavy metal halide and metallorganic compound in
19 the inert solvent, and (c) heating the mass at a
20 temperature between room temperature and 120ºC and at
21 a pressure between atmospheric pressure and 100
22 atmospheres to effect the polymerization.

24 97. The claim submitted on October 2, 1964 in the ‘840 application read:
25 A process which comprises interpolymerizing ethylene
26 with another hydrocarbon having one terminal -CH =
27 CH2 group and no other non-aromatic unsaturation, said
28 other hydrocarbon having at least 4 carbon atoms per
29 molecule, in the presence of a coordination catalyst, one
30 component of which contains a Ti-Cl bond.

32 98. Examiner Smith determined (Office action mailed Jun. 16, 1992 in
33 application 07/883,912, paper 59, pages 2-3):
34 The Declaration[s] of Drs. Corradini and Giannini cannot
35 supply to the priority documents what is not there - a
36 description of the invention in accordance with 35 U.S.C.
