Document Type and Number:
WIPO Patent Application WO/2013/118951
Kind Code:
A1
Abstract:
The present invention relates to cyclic olefin copolymers consisting of norbornene carboxylic acid alkyl ester cyclic olefin units and cyclic olefin units that contain a carboxylic acid group or a carboxylic acid metal base. The present invention also relates to a flexible substrate obtained by processing said copolymers by solvent casting or hot-melt extrusion. The resin and the flexible substrate according to the present invention have not only excellent flexibility, but also excellent heat-resistance and transparency, and therefore can be effectively used in various fields, such as flexible displays and flexible solar cells.
