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

23 As we have already noted, it was not until October 2, 1964 in the 03/710,840
24 application that the patentees submitted a disclosure (in the form of a claim) that is
25 even generally descriptive of the now claimed subject matter, i.e., appealed claim
26 1. (Amendment filed October 2, 1964, paper 40½.) The claim submitted on
27 October 2, 1964 read:
28 A process which comprises interpolymerizing ethylene with another
29 hydrocarbon having one terminal -CH = CH2 group and no other non-
30 aromatic unsaturation, said other hydrocarbon having at least 4 carbon
31 atoms per molecule, in the presence of a coordination catalyst, one
32 component of which contains a Ti-Cl bond.
