Abstract: PURPOSE: A polyamide block copolymer is provided to have excellent transparency, thermal resistance and mechanical strength, and comprises a first structure of a rigid structure and a second structure of a flexible structure. CONSTITUTION: A polyamide block copolymer comprises: a first segment comprising a repeating unit indicated in chemical formula 1 and a second repeating unit indicated in chemical formula 2; and a second segment comprising a repeating unit indicated in chemical formula 3. The weight average molecular weight of the first segment is 500-50,000 g/mol. The weight average molecular weight of the second segment is 500-50,000 g/mol. The polyamide block copolymer comprises the first segment and the second segment with the weight ratio of 1:99-60:40.
