Abstract
PURPOSE:To obtain a film excellent in oxygen barrier and heat resistance by subjecting polymers each containing a specific quantity of constituent units obtained from xylenediamine constituents and alpha, omega- aliphatic dicarboxylic acid having carbon atoms of 6 through 12, in molecular chain, to simultaneous biaxial elongation. CONSTITUTION:Thirty to one hundred % by weight of a polymer containing 50 molar % or more of constituent units consisting of one member of more of meta or paraxylenediamine constituents and alpha, omega- aliphatic dicarboxylic acid having carbon number of 6 through 12, in a molecular chain, and a polymer mixture containing 70% or less by weight of aliphatic polyamide, is molten and extruded. After cooling, these polymers are subjected to the simultaneous biaxial elongation at the elongation speed of more than 100,000%/min or more, at a temperature of 70 through 140 deg.C under the multiplication ratio of length and width, 3.5-5.5 times, and cooled. For example, nylon salt of adipic acid of metaxylenediamine and salts of adipic acid of bispropylamine derivatives of polyethylene glycol are polymerized.
