| titleOfInvention | Polymerization process |
| abstract | The invention relates to a polymerization process, the polymerization process includes contactingn a cyclic bridged metallocene catalyst represented by the following formula: nn L A (A)L B MQ n n wherein A is a divalent group bound to each of L A and L B ; each of L A andn L B are bound to M, and each Q is bound to M; L A and L B are independently selected from the group consisting of cyclopentadienyl ligands and substituted cyclopentadienyl ligands; A is a divalent bridging group comprising a heterocyclic ring comprising from 3 to 6 carbon atoms and one silyl, thus forming a 4 to 7 member divalent ring; M is a Group 4, 5, or 6 transition metal; Q is independently a halogen, a hydride, or a hydrocarbyl radical having from 1 to 20 carbon atoms; wherein n is 1 or 2;n with an activator, and optionally a support, to form an activated catalyst and, subsequently, contacting the activated catalyst with ethylene and optionally, at least one C 3 -C 8 alpha olefin comonomer. |
