STRETCHED AROMATIC-POLYAMIDE FILM |
摘要 |
<p>A stretched aromatic-polyamide film obtained by stretching an aromatic polyamide resin in the machine direction and/or transverse direction in a stretch ratio exceeding 4. The aromatic polyamide resin comprises: structural diamine units comprising 70 mol% or more m-xylylenediamine units; and structural dicarboxylic acid units comprising 80-97 mol% units of a C4-20 linear aliphatic E,i-dicarboxylic acid and 3-20 mol% units of isophthalic acid. When examined through constant-temperature crystallinzation by the depolarization intensity method, the aromatic polyamide resin has a minimum half-crystallization time of 40 to 2,000 seconds with respect to crystallization in the measurement temperature range of from the glass transition point to less than the melting point. The stretched aromatic-polyamide film is satisfactory in gas-barrier properties and transparency.</p> |
