<p>PURPOSE:To improve adhesive properties among layers, shock resistance, solvent resistance and permeability by laminating and forming modified polyolefin having specific physical properties and modified polyamide. CONSTITUTION:A large-sized vessel is manufactured in such a manner that a material is composed of modified polyolefin, which is modified by unsaturated carboxylic acid, in which the content of unsaturated carboxylic acid is 0.005-1.0wt.%, a melt flow rate of which measured in 2.16kg load is 0.01-10g/10min, a melt flow rate of which measured in 21.6kg load is 0.5-50g/10min and in which Mw/Mn>=17 holds, and Mz/Mw>=7 holds, 50-95wt.% polyamide, and 5-50wt.% polyolefin, which is modified by unsaturated carboxylic acid, in which the content of unsaturated carboxylic acid is 0.005-1.0wt.% and a melt flow rate of which measured in 2.16kg load is 0.01-10g/10min, and these compounds are mixed and modified polymide, a melt flow rate of which measured at a temperature of 235 deg.C in 2.16kg load is 0.01-7.0g/10min, is laminated. Accordingly, adhesive properties, workability and shock resistance are improved.</p> |
