MODIFIED POLYAMIDE 6T RESIN COMPOSITION HAVING HIGH IMPACT RESISTANCE, METHOD FOR PRODUCING THE SAME, AND TWIN SCREW EXTRUDER FOR PRODUCING THE COMPOSITION

摘要

<P>PROBLEM TO BE SOLVED: To provide a modified polyamide 6T resin composition having excellent impact resistance and stretchability. Ž<P>SOLUTION: The modified polyamide 6T resin composition is obtained by mixing (A) a modified polyamide 6T resin and (B) a maleic acid anhydride-modified ethylene-polypropylene copolymer (MAH-g-EPR) or a maleic acid anhydride-modified ethylene-polypropylene-diene copolymer (MAH-g-EPDM) in a weight ratio of (A):(B)=50:50 to 95:5. In the resin composition, domains of spherical modified polyamide 6T are dispersed in micron size in the MAH-g-EPR phase or MAH-g-EPDM phase. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
