Title:
極性作用基を含む環状オレフィン重合体の製造方法、これにより製造されたオレフィン重合体及びその重合体を含む光学異方性フィルム
Document Type and Number:
Japanese Patent JP5449649
Kind Code:
B2
Abstract:
A method of producing a cyclic olefin polymer having a polar functional group and a high molecular weight with a high yield in which a catalyst is not deactivated due to polar functional groups, moisture and oxygen is provided. According to the olefin polymerization method, deactivation of a catalyst due to polar functional groups of monomers can be prevented, and thus a polyolefin having a high molecular weight can be prepared with a high yield, and the ratio of catalyst to monomer can be less than 1/5000 due to good activity of the catalyst, and thus removal of catalyst residues is not required.
