Title:
ORIENTED FILM OF ADDITION POLYMER OF NORBORNENE COMPOUND ALONE, PROCESS FOR PRODUCING THE SAME AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2007/135887
Kind Code:
A1
Abstract:
[PROBLEMS] To provide an oriented film of addition polymer of norbornene compound alone that is suitable for use in processes for manufacturing electrical insulating parts or optical parts, and that excels in film stability, being free from staining problems and exhibiting a low linear expansion coefficient, and provide an easy process for producing the same. [MEANS FOR SOLVING PROBLEMS] There is provided an oriented film of addition polymer of norbornene compound alone being a film obtained by drawing a film of addition polymer of norbornene compound alone and exhibiting a linear expansion coefficient of 50 ppm/°C or below. Preferably, the draw ratio is in the range of 1.2 to 10. The oriented film is preferably a non-crosslinked film. Further, there is provided a process for producing an oriented film, comprising either at least monodirectionally drawing a film of addition polymer of norbornene compound alone in an inert gas atmosphere at temperature within the range of glass transition temperature thereof ± 50°C, or at least monodirectionally drawing a film of addition polymer of norbornene compound alone impregnated with an organic compound of specified boiling point.
