BIAXIALLY ORIENTED POLYAMIDE FILM |
摘要 |
<p>A biaxially-oriented amorphous polyamide film and the preparation thereof are described. The film exhibits good physical and optical properties. In a specific embodiment, the amorphous polyamide is a product of the polymerization of 2,2-bis(4-aminocyclohexyl)propane with a mixture of adipic acid and azelaic acid. The polymer is extruded as a sheet and biaxially oriented under described conditions to produce a clear film having a high glass transition temperature and improved elongation properties.</p> |
