Abstract:
1. A hydroxypolyamide having a structure represented by the general formula (1): wherein m and n are integers satisfying m>0, n≧0, 2≦m+n≦1,000, and 0.05≦m/(m+n)≦1, and the recurring units may be arranged blockwise or randomly; X represents at least one tetravalent organic group selected from groups represented by the following formula (2); Y represents 5-aminoisophthalic acid having at least one hydrogen atom of the amino group substituted, from which a carboxylic acid group is excluded; and Z represents at least one divalent group selected from groups represented by the following formula (4), wherein X 1 represents a divalent organic group selected from groups represented by the following formula (5); and the hydrogen atoms on each aromatic ring may be substituted with at least one group selected from the group consisting of a methyl group, an ethyl group, a propyl group, an isopropyl group, a butyl group, an isobutyl group, a t-butyl group, a fluorine atom, and a trifluoromethyl group, wherein R 8 represents a monovalent organic group; X 1 represents a divalent organic group selected from groups represented by the following formula (5); and the hydrogen atoms on each aromatic ring may be substituted with at least one group selected from the group consisting of a methyl group, an ethyl group, a propyl group, an isopropyl group, a butyl group, an isobutyl group, a t-butyl group, a fluorine atom, and a trifluoromethyl group, and wherein the hydrogen atoms on each aromatic ring may be substituted with at least one group selected from the group consisting of a methyl group, an ethyl group, a propyl group, an isopropyl group, a butyl group, an isobutyl group, a t-butyl group, a fluorine atom, and a trifluoromethyl group.
