Title:
NORBORNENE DERIVATIVE, AND (CO)POLYMER OBTAINED BY POLYMERIZING THE DERIVATIVE
Document Type and Number:
Japanese Patent JP2005281219
Kind Code:
A
Abstract:

To provide a new alicyclic structure-containing monomer capable of obtaining a polymer having extremely low birefringence and high heat resistance as well as excellent transparency and non-water absorbency.

A norbornene derivative containing an N-mesogen-substituted dicarboximide group is suitable as the alicyclic structure-containing monomer. The mesogen group is preferably a group having two or more aromatic rings (including hetero-aromatic rings) or alicyclic rings. The (co)polymer having the above various characteristics is obtained by (co)polymerizing 1-100 wt% of the derivative with 99-0 wt% of alicyclic structure-containing monomer having no mesogen group.
