PURPOSE:To provide the titled compsn. with excellent stiffness toughness and heat resistance, and discharge stability in extrusion, by blending a modified polyofied polyolefin or arom. polyamide having a variety of functional groups with a mixt. of nylon 6 or 66 and a higher polyamide. CONSTITUTION:100pts.wt. mixt. of (i) 20-95wt% polyamide having as the principal structual unit caproamide unit and/or hexamethylene adipamide unit, and (ii) 5-80wt%. polyamide obtained by melt polymn. of at least one member selected from the group consisting of 11-12C aliph. amino acids, lactams, and equimolar salts of 6-12C aliph. diamines with 6-12C aliph. dicarboxylic acids (except for hexamethylene-diammonium adipate), is mixed and kneaded with 1-40pts.wt. polyamide consisting of (i) modified polyolefin having at least one functional group selected from the group consisting of carboxylic acid (metallic salt, esters), anhydride and epoxy groups, or (ii) arom. amino acids, arom. diamines, and/or arom. dicarboxylic acids, yielding the titled compsn. |
