Abstract
Catalyst systems with single site transition metal complexes (such as quinolinyldiamide transition metal complexes), an activator, and a metal hydrocarbenyl transfer agent (preferably an aluminum vinyl-transfer agent) are disclosed for use in alkene polymerization.
Claims28
A catalyst system comprising a quinolinyldiamido transition metal complex represented by the Formula I:
- wherein:
- M is a Group 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 metal;
- J is a three-atom-length bridge between the quinoline and the amido nitrogen;
- X is an anionic leaving group;
- L is a neutral Lewis base;
- R1 and R13 are independently selected from the group consisting of hydrocarbyls, substituted hydrocarbyls, and silyl groups;
- R2, R3, R4, R5, and R6 are independently selected from the group consisting of hydrogen, hydrocarbyls, alkoxy, silyl, amino, aryloxy, substituted hydrocarbyls, halogen, and phosphino;
- n is 1 or 2;
- m is 0, 1, or 2
- n+m is not greater than 4;
- and
- any two adjacent R groups (e.g., R1 & R2, R2 & R3, etc.) may be joined to form a substituted hydrocarbyl, unsubstituted hydrocarbyl, substituted heterocyclic ring, or unsubstituted heterocyclic ring, where the ring has 5, 6, 7, or 8 ring atoms and where substitutions on the ring can join to form additional rings;
- any two X groups may be joined together to form a dianionic group;
- any two L groups may be joined together to form a bidentate Lewis base;
- and
- an X group may be joined to an L group to form a monoanionic bidentate group;
- an activator;
- and
- and a metal hydrocarbenyl transfer agent.
