Abstract
This invention relates to a supported catalyst system and process for use thereof. In particular, the catalyst system includes a pyridyldiamido transition metal complex, an activator and a support material. The catalyst system may be used for preparing ultrahigh molecular weight polyolefins.
Claims24
A supported catalyst system comprising:
- (i) a pyridyldiamido transition metal complex having the general formula (I);
- (ii) an activator;
- and
- (iii) a support material;
- wherein:
- M is a Group 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 metal;
- Z is —(R14)pC—C(R15)q—,
- where R14 and R15 are independently selected from the group consisting of hydrogen, hydrocarbyls, and substituted hydrocarbyls, and wherein adjacent R14 and R15 groups may be joined to form an aromatic or saturated, substituted or unsubstituted hydrocarbyl ring, where the ring has 5, 6, 7, or 8 ring carbon atoms and where substitutions on the ring can join to form additional rings,
- p is 0, 1 or 2, and
- q is 0, 1 or 2;
- R1 and R11 are independently selected from the group consisting of hydrocarbyls, substituted hydrocarbyls, and silyl groups;
- R2 and R10 are each, independently, -E(R12)(R13)- with E being carbon, silicon, or germanium, and each R12 and R13 being independently selected from the group consisting of hydrogen, hydrocarbyls, alkoxy, silyl, amino, aryloxy, substituted hydrocarbyls, halogen, and phosphino, R12 and R13 may be joined to each other or to R14 or R15 to form a saturated, substituted or unsubstituted hydrocarbyl ring, where the ring has 4, 5, 6, or 7 ring carbon atoms and where substitutions on the ring can join to form additional rings, or R12 and R13 may be joined to form a saturated heterocyclic ring, or a saturated substituted heterocyclic ring where substitutions on the ring can join to form additional rings;
- R3, R4, and R5 are independently selected from the group consisting of hydrogen, hydrocarbyls (such as alkyls and aryls), substituted hydrocarbyls, alkoxy, aryloxy, halogen, amino, and silyl, and wherein adjacent R groups (R3 & R4, and/or R4 & R5) may be joined to form a substituted or unsubstituted hydrocarbyl or 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;
- L is an anionic leaving group, where the L groups may be the same or different and any two L groups may be linked to form a dianionic leaving group;
- n is 0, 1, 2, 3, or 4;
- L′ is neutral Lewis base;
- and
- w is 0, 1, 2, 3 or 4.
