CONTAINING VINYL "<D>. [Mol% comonomer + 0.1] ^ a ^ x 10 ^ a ^ x b. Polymeric compositions of matter are described, which comprise total polymeric chains according to formula (1), where the = -0.24 per 1000 carbon atoms is greater than or equal to 8000 <sym> M ~ n ~. The invention includes a method for preparing these polymeric products comprising contacting one or more olefinic comonomers with a catalyst system containing a transition metal catalyst and an alumoxane, where the ratio of aluminum to transition metal is 10: 1 unless, or equal to 220: 1 (Al: Me). The process conditions of the invention allow for characteristics of predictable macromers of both molecular weight and vinyl unsaturation. |
