Title:
METHOD FO PRODUCING CAST FILM OF ADDITION POLYMER OF NORBORNENE COMPOUND
Document Type and Number:
Japanese Patent JP2016169349
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently producing a cast film of an addition polymer of a norbornene compound which is excellent in transparency and has excellent slipperiness (film-winding properties).SOLUTION: There is provided a method for producing a cast film that includes applying a resin solution in which an addition polymer of a norbornene compound is dissolved in an organic solvent onto a resin film support, forming a flow casting film, evaporating the organic solvent, and then peeling a resin film support, where a substance is used as the resin film support, of which surface roughness (PV) represented by the maximum height difference of the surface is in a range of 0.010 to 0.300 μm and a wet tension is in a range of 50-75 mN/m.SELECTED DRAWING: None
