Abstract:
An oxidation polymer of a substituted phenol, which is obtained by oxidative polymerization of at least one substituted phenol compound selected from the group consisting of a substituted phenol compound represented by the following formula (Ia), and a 2,6-di-substituted phenol compound represented by the following formula (Ib), wherein the oxidation polymer has a number-average degree of polymerization of 3 or more and wherein the oxidation polymer has a crystal melting point providing crystal melting calories of from 5 J/g to less than 200 J/g, at âˆ’100Â° C. to less than 300Â° C. after melt-cooling: wherein, in formula (Ia), R1, R2, R3, and R4 each individually represent a hydrogen atom, a substituted or unsubstituted hydrocarbon group, a substituted or unsubstituted hydrocarbon oxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted mercapto group, or a halogen atom; R1 and R2, R2 and R3, or R3 and R4 may form a ring; provided that at least one of R1 to R4 represents a substituted or unsubstituted, saturated hydrocarbon group having 10 or more carbon atoms, and R1 and/or R4 represent a hydrogen atom; and wherein, in formula (Ib), R11 represents a substituted or unsubstituted, saturated hydrocarbon group having 15 or more carbon atoms, and R12 is the same group as R11, or when R12 is different from R11, R12 represents a substituted or unsubstituted hydrocarbon group, a substituted or unsubstituted hydrocarbon oxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted mercapto group, or a halogen atom.
