C08G 69/26 - Polyamides derived from amino carboxylic acids or from polyamines and polycarboxylic acids derived from polyamines and polycarboxylic acids
A method of producing a biaxially stretched, multi-layered polyamide film which includes a step of biaxially stretching a non-stretched laminate film composed of a layer mainly made of a polyamide resin and a layer mainly made of an aliphatic polyamide resin. The biaxial stretching is made by a roll/tenter successive biaxial stretching method. The polyamide resin is composed of a diamine constitutional unit mainly made of m-xylylenediamine units and a dicarboxylic acid constitutional unit mainly made of units derived from an .alpha., .omega.-aliphatic dicarboxylic acid having 6 to 12 carbon atoms. The non-stretched laminate film is cooled by a cooling roll having a temperature within a limited range and then successively and biaxially stretched. With such a production method, the biaxially stretched, multi-layered polyamide film is excellent in the gas barrier properties, pinhole resistance, flexibility, and impact resistance.
A stretched polyamide film including at least one stretched layer made of a mixed resin containing a polyamide resin and a modified polyester-based elastomer Y The polyamide resin X is mainly constituted by m-xylylenediamine unit and C6-12 .alpha.,.omega.-aliphatic dicarboxylic acid unit. The modified polyester- based elastomer is graft-modified with an ethylenically unsaturated carboxylic acid or its anhydride. Such stretched polyamide film is drastically improved in the flexibility, impact resistance and pin-hole resistance with little reduction in the gas-barrier properties while retaining an enough transparency to practical use.

C08L 77/06 - Polyamides derived from polyamines and polycarboxylic acids
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 .alpha.,.omega.-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.
