Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) Published: — with international search report (Art. 21(3)) (54) Title: LINEAR ETHYLENE CYCLIC OLENFIN POLYMERS (57) : A polymer obtained by a solution polymerization process comprising within a range from 0.5 to 20 wt% of cyclic olefin derived units, within a range from 0 wt% to 15 wt% C4 to C12 a- olefm derived units, the remainder being ethylene derived units; and having a Mw/Mn of less than 2.5; a weight average molecular weight (Mw) within a range from 80,000 to 300,000 g/mole; and a g' value of greater than 0.95. The polymer may be formed in a solution polymerization process comprising combining in a solution cyclic olefins, ethylene, hydrogen and optionally C4 to C12 a-olefms with a single-site catalyst to form the polymer, wherein the single-site catalyst is most preferably selected from unsymmetrical Group 4 bis-bridged cyclopentadienyl metallocenes.
