Abstract:
1. A phenolic hydroxy group-containing rubber-modified polyamide resin obtained by reaction of (1) one or both kinds selected from the group consisting of a butadiene polymer which is terminated with a carboxy group at both ends and has a weight average molecular weight of 1,000 to 10,000 and an acrylonitrile-butadiene copolymer which is terminated with a carboxy group at both ends and has a weight average molecular weight of 1,000 to 10,000 with (2) a polyamide resin terminated with an amino group at both ends and having a structure represented by the following formula (A), wherein, m and n are average values and represent 0.01≦n/(m+n)≦0.30, m+n represents a positive number of 5 to 200, and Ar represents a group represented by the following formula (1) wherein, R 1 is a hydrogen atom, a fluorine atom, a hydroxy group or a substituent having 1 to 6 carbon atoms which may contain O, S, P, F and Si, R 2 represents a direct bond or a divalent linking group of 0 to 6 carbon atoms which may contain O, N, S, P, F, and Si, an b is an average substituent number and represents a positive number of 0 to 4, which has a phenolic hydroxy group-containing aromatic polyamide segment having a structure represented by the above formula (A) and a butadiene polymer or acrylonitrile-butadiene copolymer segment selected from the following formula (B-1) or (B-2) wherein, each of x, y and z is an average value, x represents a positive number of 5 to 200, y and z represent 0<z/(y+z)<0.09, and also y+z is a positive number of 10 to 200, wherein the molar ratio of the repeating unit represented by the following formula (B-3) and the repeating unit represented by the following formula (B-4)
