Title:
PRODUCTION OF CYCLOOLEFIN POLYMER
Document Type and Number:
Japanese Patent JP3416243
Kind Code:
B2
Abstract:
PURPOSE: To produce a cycloolefin polymer having a high viscosity number by polymerizing a polycyclic olefin in the presence of a catalyst comprising an aluminoxane and a specific metallocene compd.
CONSTITUTION: Based on the total monomers, 0.1-100 wt.% polycyclic olefin [e.g. one of formula I or II (wherein R1 to R4 are each H or a hydrocarbon radical), 0-99.9 wt.% monocyclic olefin (e.g. cyclopentene), and 0-99.9 wt.% acyclic 1-olefin (e.g. ethylene) are copolymerized at 20-150°C and 0.01-64 bar in the presence of a catalyst comprising an aluminoxane of formula III and/or IV (wherein R13 is a 1-6C alkyl, phenyl, or the like; and (n) is 2-50) and a metallocene compd. of formula V [wherein M1 is Ti, Zr, or the like; R14 and R15 are each H, a halogen, or the like; R16 is fluorenyl or indenyl; R17 is cyclopentadienyl; and R18 is a group of formula VI or VII (wherein M2 is Si; and R19 and R20 are each H, a 1-10C alkyl, or the like) or the like] [pref. dichlorodimethylsilanediyl(9-(2,7-di-t-buty)fluorenyl)cyclopentadienylzirconium.
