Abstract

Polymeric compositions of matter are described comprising olefin polymer chains having Mn of about 400 to 75,000, a ratio of vinyl groups to total olefin groups according to formula (1), where a = -0.24 and b = 0.8, and where the total number of vinyl groups per 1000 carbon atoms is greater than or equal to 8000 Mn. The invention includes a method for preparing these polymeric products comprising contacting one or more olefin comonomers with a catalyst system containing a transition metal catalyst compound and an alumoxane wherein the aluminum to transition metal ratio is from 10:1 to less than or equal to 220:1 (Al:Me). The process conditions of the invention permit predictable macromer characteristics of both molecular weight and vinyl unsaturation.

Claims

AMENDED CLAIMS[received by the International Bureau on 12 August 1998 (12.08.98); original claims 1 and 6 amended; remaining claims unchanged ( 1 page)]
1. A composition of matter comprising olefin polymer chains having Mn of about 1500 to 75,000, a ratio of vinyl groups to total olefin groups according to the formula
(1) vinyl groups/ olefm groups > [comonomer mole percent + 0.1]" x 10Λχb
where, a = -0.24 and b = 0.8, and where the total number of vinyl groups per 1000 carbon atoms is greater than or equal to 8000-*-Mn.
2. The composition of claim 1 wherein a =* -0.20.
3. The composition of claim 1 wherein a = -0.18 and b = 0.83.
4. The composition of claim 1 wherein a = -0.15 andb = 0.83.
5. The composition of claim 1 wherein said olefin polymer comprises one or more of the group consisting of ethylene, C3-C]2 α-olefins, isobutylene and norbomene.
6. A method for preparing polymers having high levels of vinyl unsaturation comprising contacting, under batchwise, solution polymerization conditions, one or more olefin monomers with a catalyst solution composition containing a transition metal catalyst compound and an alumoxane wherein the aluminum to transition metal ratio is from 10:1 to 220.1.
7. The method of claim 6 wherein the aluminum to transition metal ratio is from 20: 1 to 140:1.
