(A) a random polyamide comprising
(a) at least one isphthaloyl diamine component represented by the general formula (I) of
wherein R⁰ represents a divalent hydrocarbon group of 4-25 carbons, in a total amount of 50-100 mole %; and
(b) at least one diacyloyl diamine component represented by the general formula (II) of
-[NH-R⁰-NHCO-Ar-CO)-
wherein R⁰ is as defined above and Ar represents a divalent aromatic hydrocarbon group of 6-20 carbons but is not a 1,3-phenylene group, in a total amount of 50-0 mole %, and
(B) a polyamide comprising:
(c) at least one diamine component of 4-25 carbons or dicarboxylic acid component of 4-20 carbons which have no aromatic nuclei; or
