Abstract:
1. A polyamide combination comprising: a first polyamide comprising (i) a structure unit represented by Chemical Formula 2, and (ii) a structure unit represented by Chemical Formula 3; and a second polyamide (i) consisting of a structure unit represented by Chemical Formula 3, wherein, in Chemical Formula 2, R R R n3 is an integer ranging from 1 to 4, n5 is an integer ranging from 0 to 3, n3+n5 is an integer of 1 to 4, n4 is an integer ranging from 1 to 4, n6 is an integer ranging from 0 to 3, and n4+n6 is an integer of 1 to 4, wherein, in Chemical Formula 3, R R R R n7 and n8 are each independently integers ranging from 0 to 4, wherein the electron withdrawing group is —CF wherein the first polyamide comprises the structure unit represented by Chemical Formula 2 in an amount of from about 10 mol % to about 30 mol % based on the total moles of the structure units of the first polyamide, wherein the first polyamide has a weight average molecular weight (Mw) of from about 101,000 g/mol to about 176,000 g/mol, and wherein the first polyamide and the second polyamide are included at a weight ratio of the first polyamide to the second polyamide of from about 20:80 to about 30:70.
