8 60. Claims 1, 9, and 16, which are representative of the appealed claims,
9 are reproduced as follows:
10 1. A process which comprises polymerizing
11 ethylene with an alpha-olefin, CH2=CHR, wherein R is a
12 saturated aliphatic radical with 2 or more carbon atoms or
13 a cycloaliphatic radical, in the presence of a catalyst
14 obtained by reacting an aluminum alkyl compound with a
15 catalytic titanium halide compound.
16
17 9. A process for preparing a copolymer
18 comprising copolymerizing monomeric olefin molecules
19 comprising a monomeric vinyl hydrocarbon having the
20 formula CH2=CHR, wherein R is a saturated aliphatic
21 radical having at least 2 carbon atoms or is a
22 cycloaliphatic radical, in the presence of a catalyst
23 comprising a catalytic aluminum alkyl compound and a
24 catalytic titanium halide compound.
25
26 16. A process according to claim 9 wherein the
27 monomeric olefin molecules comprise ethylene, the
28 monomeric vinyl hydrocarbon is selected from the group
29 consisting of 1-butene, 1-pentene, and 1-hexene, the
30 alkyl of the catalytic aluminum alkyl compound is
