| titleOfInvention | Preparation of aromatic polyamide film |
| abstract | PURPOSE: To obtain the titled film, excellent in transparency, toughness, electrical resistance, etc., and suitible as an insulating material, etc., by the wet molding of a composition containing an aromatic polyamide, an amide solvent and a solubilization aid, in a specified proportion, in a specified coagulating bath. n CONSTITUTION: A stock solution composition is obtained, by mixing (A) an aromatic polyamide (e.g., m-phenylene-isophthalamide polymer), (B) an amide solvent (e.g., N-methylpyrrolidone-2) and (C) a solubilization aid (e.g., CaCl 2 ), in such a proportion as to satisfy formulas I and II (wherein a, b and c respectively represent pts.wt. of said components A, B and C). A film is obtained, by introducing the composition, through an orific, etc., into a coagulating bath, selected from (1) an aqueous solution of an inorganic salt (e.g., aqueous solution of CaCl 2 ), (2) an aqueous solution of an organic solvent (e.g., aqueous solution of an alkylen glycol) and (3) a halogenated hydrocarbon (e.g., methylene chloride). When the stock solution composition is highly viscous, it is preferable to introduce it into the bath, after passing it once through a gaseous medium such as air. n COPYRIGHT: (C)1981,JPO&Japio |
