Title:
CYCLOOLEFIN POLYMER
Document Type and Number:
Japanese Patent JP2002348324
Kind Code:
A
Abstract:

To provide a polymer having a polycyclic cycloolefin, and having a high viscosity and a high glass transition temperature.

A polycyclic cycloolefin such as norbornene in an amount of 0.1-100 wt.%, and at least one of 0-99.9 wt.% of a monocyclic cycloolefin and 0-99.9 wt.% of a noncyclic 1-olefin, all based on the total amount of the monomers are polymerized in the presence of a catalyst composed of a specific metallocene as a transition metal component and a linear and/or cyclic aluminoxane, at -78 to 150°C and at 0.5-64 bar, in a solution, dispersion, molten monomer, or vapor state.
