| titleOfInvention | Microcellular aromatic polyamide film |
| abstract | PURPOSE:To obtain the subject film, having continuous micropores with specific values or below of humidity expansion coefficient and shrinkage stress in the longitudinal direction of the film and hardly any dimensional change, excellent in heat, chemical resistance, etc., and useful as electrolytic capacitors, etc. CONSTITUTION:The objective film, obtained by dissolving 2-40wt.% aromatic polyamide consisting of a polymer preferably containing >=50mol% recurring units expressed by the formula (p+q>=1), etc., and 0-100wt.% (based on the polymer) inorganic salt (e.g. calcium chloride) in an aprotic polar solvent (e.g. dimethylformamide) to provide a film-forming stock solution, regulating the resultant stock solution so as to afford 100-10000P viscosity, casting the regulated solution onto a support, such as a metallic drum, longitudinally drawing the film in water at 0 to <=90 deg.C by a wet film-forming method (preferably in a water bath) to prepare a microporous film and having <=50X10<-6>cm/cm/% RH humidity expansion coefficient and <=2kg/mm<2> shrinkage stress in the longitudinal direction thereof within a temperature range of 100-300 deg.C. |
