Abstract
Provided is an end modified polyamide resin containing 1 to 20% by mass of an end structure represented by the following general formula (I) and 0.1 to 5% by mass of an end structure represented by the following general formula (II): —X—(R1—O)m—R2 (I) wherein m represents 2 to 100; R1 represents a divalent hydrocarbon group having 2 to 10 carbon atoms, and R2 represents a monovalent hydrocarbon group having 1 to 30 carbon atoms; —X— represents —NH—, —N(CH3)— or —(C═O)—; and m R1s in the general formula (I) may be the same or different, and —Y—R3 (II) wherein R3 represents a monovalent hydrocarbon group having 1 to 30 carbon atoms; and —Y— in the general formula (II) represents —(C═O)— when X in the general formula (I) is —NH— or —N(CH3)—, Y in the general formula (II) represents —NH— or —N(CH3)— when X in the general formula (I) is —(C═O)—.
