Document Type and Number:
WIPO Patent Application WO/2018/147618
Kind Code:
A1
Abstract:
One embodiment relates to a method for preparing a polyamide-imide film which is colorless and transparent and has good mechanical properties, easily and efficiently in terms of yield. Particularly, the embodiment relates to a preparation method capable of obtaining a polyamide-imide film of which the optical characteristics, mechanical properties and flexibility are harmoniously improved without complicated processes, by controlling the amount of imide repeating units and amide repeating units constituting the polyamide-imide film.
