Title:
METALLOCENE DERIVED FROM FULLERENE
Document Type and Number:
Japanese Patent JP3205903
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a new metallocene derived from fullerene having high activity, suitable as a catalyst for preparing an olefin polymer.
SOLUTION: This metallocene is shown by the formula Rm-F-(MXpAq)n [F is a fullerene nucleus; R is a 1-20C alkyl, a 6-40C aryl, a 1-40 alkylaryl or a 7-40C arylalkyl; M is a transition metal; X is a halogen, a hydride or an aryl; A is a (substituted) cyclopentadienyl, a (substituted) indenyl or a (substituted) fluorenyl; (m) and (n) are each 1-10; (p) and (q) are each a positive integer and the sum of 1+p+q is equal to the oxidation state of M] such as biscyclopentadienylzirconium. The metallocene derived from fullerene of the formula is obtained, for example, by reacting metallocene MHXpAq with a fullerene nucleus.
