PURPOSE: The titled composition having improved impact resilience, compression strength and impact strength, obtained by blending a polyamide resin with an acid-modified polyolefin and an epoxy compound in a specific ratio in a molten state, reacting them. n CONSTITUTION: (A) A polyamide resin (e.g., nylon 11, etc.) and/or polyether polyamide elastomer is blended with (B) an acid-modified polyolefin (e.g., ethylene- butene-1-maleic acid (anhydride) copolymer, etc.) containing ≥50mol% 1-olefin, (C) an epoxy compound (e.g., bisphenol, etc.) in a reactor or an extruder at 100W 350°C in a molten state, and reacted. A blending ratio of the component A/B by weight is 20/80W95/5, preferably 50/50W90/10, and a blending ratio of the component C/(A+B) is 0.1/100W20/100, preferably 1/100W15/100. n COPYRIGHT: (C)1985,JPO&Japio |
