1 polymers may comprise as high as 30% or even up to
2 55% of the mixture and have high molecular weights and
3 fiber forming properties. The amorphous polymers may
4 also have relatively high molecular weights and may
5 exhibit rubber-like properties. [Emphasis added.]

7 94. The ‘840 specification further stated (pages 4-5):
8 [I]t has been found, also, that even when ethylene is
9 polymerized with the aid of the special promoters
10 obtained by reaction of the heavy metal and metal alkyl
11 compounds, in the ratios proposed for promoting
12 ethylene polymerization, the presence of any substantial
13 amount of the higher olefins inhibits polymerization of
14 the ethylene, while the higher olefins, if they react at all,
15 do so only at very low reaction rates and, in any case,
16 without yielding polymers of the type with which this
17 invention is concerned. [Emphasis added.]

19 95. The ‘840 specification states (page 10):
20 The method of this invention may be used for
21 polymerizing vinyl hydrocarbons of the formula given
22 including propylene, butene-1, pentene-1, hexene-1,
23 styrene, and so on, as well as mixtures thereof and
24 mixtures of the vinyl hydrocarbon with small amounts of
25 ethylene. [Emphasis added.]
26 96. Original claim 1 of 03/710,840 read:
27 A process for producing polymerizates of unsaturated
28 hydrocarbons of the general formula

32 where R is a radical containing 1 to 16 carbon atoms and
33 is selected from the group consisting of alicyclic,
34 aromatic and saturated aliphatic radicals, said
35 polymerizates being selected from the group consisting
36 of high molecular weight polymerizates comprising
