FULLY AROMATIC POLYAMIDE, FULLY AROMATIC POLYAMIDE POROUS FILM AND SEPARATOR FOR NONAQUEOUS ELECTROLYTIC SOLUTION SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a fully aromatic polyamide which hardly causes the decomposition even at a high voltage, a fully aromatic polyamide porous film using it, a separator for a nonaqueous electrolytic solution secondary battery containing the film and a nonaqueous electrolytic solution secondary battery containing the separator. SOLUTION: [1] The fully aromatic polyamide having a homo value of -8.5 eV or less of all nitrogen atoms in a molecular model, which is determined by the molecular orbital method calculation. [2] The fully aromatic polyamide porous film comprising the fully aromatic polyamide in [1]. [3] The separator for the nonaqueous electrolytic solution secondary battery containing the film in [2]. [4] The nonaqueous electrolytic solution secondary battery containing the separator in [3].
