Document Type and Number:
Japanese Patent JP2009046615
Kind Code:
A
Abstract:

To provide a norbornene-based ring-opened (co)polymer, which has high solubility to organic solvent, in addition to excellent transparency and heat resistance, and further specific birefringence and wavelength dependency.

The polymer comprises a structural unit (I) represented by the general formula (I), wherein X preferably represents -CH2CH2-, and R1-R5 each represents a hydrogen atom, a halogen atom, a 1-30C hydrocarbon group or a polar group, any one of R2-R5 being a singly dehydrogenated product of an aromatic compound having a molar extinction coefficient of 10-100,000 at a maximum absorption wavelength.
