ABSTRACT:
A process for producing a polydiacetylene molecular orientated film is disclosed, which comprises a first step of forming a polydiacetylene film on a base using a diacetylene monomer or a polydiacetylene, a second step of unidirectionally rubbing the polydiacetylene film with a cloth at least once, a third step of building up a diacetylene monomer on the film, and a fourth step of polymerizing the diacetylene monomer film formed in the third step in a solid phase, said second to fourth steps being carried out once or more in this order. The resulting orientated film exhibits high orientation and crystallinity without limitations in film thickness, film area, and polymer materials.
