Abstract:
1. A polyamide block copolymer comprising at least one first segment, each being the same or different and each independently comprising a structural unit represented by the following Chemical Formula 2, and a structural unit represented by the following Chemical Formula 3; and at least one second segment each being the same or different and each independently comprising a structural unit represented by the following Chemical Formula 1, and a structural unit represented by the following Chemical Formula 3: wherein, in Chemical Formula 1, R R selected from the following chemical formulas: wherein, in the above chemical formulas, R wherein n9 and n12 to n18 are each independently integers ranging from 0 to 4; and n10 and n11 are each independently integers ranging from 0 to 3; R n1 and n2 are each independently integers ranging from 0 to 4; and “*” represents a point of attachment to a subsequent structural unit; 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; the sum of n3 and n5 is an integer of 4 or less; n4 is an integer ranging from 1 to 4; n6 is an integer ranging from 0 to 3; the sum of n4 and n6 is an integer of 4 or less; and “*” represents a point of attachment to a subsequent structural unit; wherein, in Chemical Formula 3, R R R R n7 and n8 are each independently integers ranging from 0 to 4; and “*” represents a point of attachment to a subsequent structural unit, wherein the at least one first segment and the at least one second segment are not identical to each other, wherein the at least one first segment has a weight average molecular weight of about 500 grams per mole to about 50,000 grams per mole, wherein the at least one second segment has a weight average molecular weight of about 500 grams per mole to about 50,000 grams per mole, and wherein the structural unit represented by the above Chemical Formula 3 comprised in the at least one second segment is comprised in an amount of more than about 60 mole % based on the entire amount of all the structural units comprised in the second segment.
