Abstract:
1. An aromatic amide block copolymer comprising an aromatic amide compound unit represented by the following general formula (1): wherein R 1 and R 2 each independently represents a divalent alkylene group having from 1 to 20 carbon atoms; and Ar 1 and Ar 2 each independently represents a divalent arylene group having from 6 to 20 carbon atoms, and a structural unit represented by the following general formulae (2) and/or (3): wherein G 1 and G 2 each represents a polyester residue; G 3 represents a diol compound residue or a polyol compound residue; and X represents at least one chain extending component unit selected from groups represented by the following general formulae (4) to (5): wherein R 3 s each independently represents a divalent alkylene group having from 2 to 20 carbon atoms; R 4 represents a carbonyl group or a divalent organic group having from 2 to 20 carbon atoms; and p and q each represents 0 or 1, wherein R 5 represents a divalent hydrocarbon group having from 2 to 20 carbon atoms, and having a weight average molecular weight, as reduced into standard polystyrene measured by the gel permeation chromatography, of from 10,000 to 1,000,000.
