POLYAMIDE RESIN COMPOSITION AND FOAM MOLDED BODY CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin composition capable of providing a foam molded body having high foaming ratio, uniform bubble diameter and excellent in surface appearance with good operability.SOLUTION: There is provided a polyamide resin composition containing 100 pts.mass of (A) a polyamide resin having relative viscosity under a condition of a temperature of 26°C and concentration of 1 g/100 ml in a range of 2.0 to 4.0 and 0.05 to 5 pts.mass of (B) a (meth)acrylic acid ester compound having two or more (meth)acrylic groups or one or more (meth)acrylic group and one or more glycidyl group or vinyl group in a molecule with 96% sulfuric acid as a solvent and having specific distortion hardening coefficient and melting tensile at 240°C of 20 to 200 mN.SELECTED DRAWING: Figure 1
