POLYAMIDE RESIN COMPOSITION AND FILM THEREFROM

摘要

A polyamide resin composition obtained by melting and kneading (A) a first polyamide containing not less than 90 mol%, based on the total recurring units, of a m-xylylene adipamide unit of the formula, and (B) a second polyamide showing a semicrystallization time of not more than 30 seconds in a constant-temperature crystallization at 160 DEG C and having a solubility parameter in the range of 13 +/- 1.5 (C) under the conditions where the following relationship is satisfied, $wherein\; C\; is\; a\; proportion\; (wt.\%)\; of\; the\; first\; polyamide\; based\; on\; the\; total\; weight\; of\; the\; first\; and\; second\; polyamides,\; and\; R\; is\; a\; ratio\; of\; the\; melt\; viscosity\; of\; the\; first\; polyamide\; to\; the\; melt\; viscosity\; of\; the\; second\; polyamide\; at\; a\; temperature\; higher\; by\; 20\; DEG\; C\; than\; the\; melting\; point\; of\; that\; one\; of\; the\; first\; and\; second\; polyamides\; which\; has\; a\; higher\; melting\; point\; than\; the\; other,\; provided\; that\; C\; is\; in\; the\; range\; of\; 20\; to\; 95\; (wt.\%);\; and\; a\; film\; produced\; therefrom.\; s$
